[Ken Feyl <address@hidden>]

Dear friends, thank you for your superb effort in TeXmacs. It looks 
extraordinarily
cool. I do, however, have one rather crippling problem.

Using TeXmacs under the usual XDarwin on my OS X 10.2.2 system running at
400 MHz with 384 MB RAM, I observe a rather predictable occurrence of this
malloc error:

malloc[11452]: Deallocation of a pointer not malloced: 0xd19454; This could
be a double free(), or free() called with the middle of an allocated block;
Try setting environment variable MallocHelp to see tools to help debug pure
virtual method called

It happens whenever I move the cursor through the contents of a file. I can
add on to the end of a file, but whenever I start to move back through the
file (to correct a mistake, for instance) it may last a couple seconds or
so but finally everything suddenly dies and leaves me with only this malloc
error. However, I should emphasize that if I simply add on to the end of
the file, there are no problems. But I do not know what to do about this
problem. I cannot use TeXmacs unless I can fix this behavior, and searching
the archives hasn't been much of a help.

I don't observe this behavior in any other program... only TeXmacs. Does
anyone know what I can perhaps do to fix this? Thanks! BTW, I compiled TeXmacs
from source. BTW, I also tried it on 1.024 and 1.023... same problem.

Ken
