Hello,
Now I understand how to build Debian package with debug symbols. For new debhelpers, it is very easy - no essential extra work is needed.
The first thing is that you need to rewrite debian/rules. Your original version (https://build.opensuse.org/package/view_file/home:DenisRx:TeXmacs/TeXmacs/debian.rules?expand=1) is unnecessarily over-complicated and error-prone. In order to customize, you only need to write override_dh_*. In this way, you can still invoke original dh_* programs.
A sample and explanation of debian/rules could be found at https://www.debian.org/doc/manuals/maint-guide/dreq.en.html#rules
The second thing is that Debian sets default CFLAGS and CXXFLAGS before running ./configure which includes '-O2', therefore debuild will ignore TeXmacs' platform oriented optimizations. Therefore I added DEB_CFLAGS_MAINT_STRIP and DEB_CXXFLAGS_MAINT_STRIP to exclude possible '-O1' and '-O2'. By default, it still contains "-g".
After setting these, build the package normally by "debuild -b -uc -us", the dpkg will *automatically* strips the debug symbols into a dbgsym package. No further efforts are needed! Consequently, I can load debug symbols with gdb:
Reading symbols from /usr/lib/x86_64-linux-gnu/TeXmacs/bin/texmacs.bin...Reading symbols from /usr/lib/debug/.build-id/8a/0cdb8dbda86c7498da5e9a477128518b27fe88.debug...done.
And the call stack is much better, such as:
#6 0x00000000005bde89 in tm_throw(char const*) (msg=0x140d9b0 "guile could not be found") at ./Kernel/Abstractions/basic.cpp:197
The last thing, which is somewhat irrelevant, is that in the configuration (configure.in), it is set that
CFLAGS=${CFLAGS:=""}if I modify it to CFLAGS:="-g" and CXXFLAGS:="-g", then by default the result will contain debug symbols (Debian is not concerned because dpkg-buildflags set "-g" by default). Note that "-g" is compatible with "-O3".
CXXFLAGS=${CXXFLAGS:=""}
I suggest @Joris to include this (call stacks with function names are much more comprehensible than unknown addresses and question marks).
By the way, by rebuilding, the bug of crashing of \footnote, and crashing while searching disappear. I use the same code base as your build, because I downloaded the source code from your OpenSuse directory.
Best wishes,

Dear Frank,--
the packages we provide are built using the » Open build service »form
openSuse. You can access to this public directory at
https://build.opensuse.org/project/show/home:DenisRx:TeXmacs
Time to time I build intermediate versions on this site which are not pushed
on texmacs.org
Currently they are no debug information generated but I’ll keep that in mind
for the near futur if it is possible to generate it.
But texmacs it’s not easy to debug and more often having the stack with
symbols doesn’t give many extra information as the code is optimised. I would
suggest to build your own version form the sources with the debug flag and
some others debug stuff activated inside (especially for the guile code).
Best regards,
Denis

Dear Denis Raux,
Could you please also join -dbgsym packages in the repo, so that when TeXmacs
crashes we can load it with gdb to obtain a more detailed call stack or
memory dump to facilitate the debug process?

Hi Arturo,--
If you have any installation or upgrading problems with the Debian/Ubuntu
packages from our website, then please write to Denis Raux (in the CC),
who maintains these packages, and explain very precisely what you did
(version of your OS, old/new version of TeXmacs).
Best wishes, --Joris

Hi Frank.
Many thanks for your email. I see this information on the Texmacs site
and make this installation on Linux Mint. Texmacs was working good,
but at some point, after an update, Texmacs stop working. I will try
Debian or Ubuntu.
Best Wishes.
Arturo

Hello,
There is no problem for Debian and Ubuntu. I am using Debian.
https://texmacs.org/tmweb/download/linux.en.html
Look at the paragraph
In the cases of Debian and Ubuntu , we also propose a way to add a
TeXmacs repository to your package manager; this makes it easy to
detect and install new versions.
If you want to download packages and install TeXmacs manually, see
https://texmacs.org/tmweb/download/linux-packages.en.html#debian
Especially for a package of guile-1.8:
Important : In some cases you should have to install the guile
additional package manually. You can dowmload it here.

Dear friends.
Excuse my rough english.
I'm find some troubles with Linux distribuitions and Texmacs.
Debian based: ubuntu, sparkylinux, MX18, Linux Mint, etc., are
not supporting Guile 1.8. 9 They say tht it's "deprecated"). So
Texmacs is not available.
At moment I can use Texmacs only in Centos. But Centos is very
heavy in Desktop. I am using Texmacs to write lectures and
essays of philosophy.
My experience is: you can install Texmacs and dependencies from
the repositories only in Centos, Fedora, Mageia (I'm not certain
about this especifically, theyhave guile 1.8 on they
repositories). But Centos have a weird behaviour im my Desktop
and Laptop, and Fedora have a crazy release cycle (tehey are
neurotic about "the new"); Mageia have just a one year cycle.
Someone is having the same trouble with Texmacs and Linux?
Thanks
Arturo
