Greeting, TeXmacs users!

I'm relearning linear algebra algorithms for my current project,
and i've found, that TeXmacs good for «notepad» workflows, so
i'm using it to visualise matrices and other relative data.

But i'm hit strange error, and cannot understand what is causing
it.

Attachment contains the Scheme code, which implements inverse
matrix calculation via lup decomposition (Cormen algorithm).
When i run this code (see the Testing section at the end of
file) with Guile Scheme from console, i always get expected
results. For instance

$ guile mmul.scm 
(4798812820 2947166038 8605901937 1668829253) ; <- this is the A matrix
(3262456359 8838015003 1557481481 3270092634)
(171172813 9409289762 1357419403 4800934199)
(9432354808 1354480021 2510360485 5482916884)

(9432354808 1354480021 2510360485 5482916884) ; <- this is reconstructed P * 
A matrix
(171172813 9409289762 1357419403 4800934199)
(4798812820 2947166038 8605901937 1668829253)
(3262456359 8838015003 1557481481 3270092634)

3 ; <- This is P matrix representation
2
0
1
7

(1 0 0 0) ; <- this is A * (inverse A)
(0 1 0 0)
(0 0 1 0)
(0 0 0 1)

But, when i load this code in TeXmacs Scheme session i get
strange console output. For instance (in the result of
evaluating (load "mmul.scm"))

I do not understand completely, what is going on and what is
the problem. May anyone provide any help?
