So I've now rebuilt guile-1.4 and TeXmacs-1.0.0.20 with compat-gcc package:

$ strings -a TeXmacs-1.0.0.20/bin/texmacs.bin|grep GCC|sort|uniq
GCC: (GNU) 2.96 20000731 (Red Hat Linux 7.3 2.96-110)
GCC: (GNU) 3.2 20021021 (Red Hat Linux 8.0 3.2-11)

$ strings -a /usr/lib/libguile.so.9.0.0 |grep GCC|sort|uniq
GCC: (GNU) 2.96 20000731 (Red Hat Linux 7.3 2.96-110)
GCC: (GNU) 3.2 20021021 (Red Hat Linux 8.0 3.2-11)

In this configuration fully-optimized TeXmacs is stable (at least in my tests)
both statically and dynamically linked.

If TeXmacs is otherwise built optimized using GCC-3.2 then it crashes.
The crash is after the sequience of "document->update->all" which rebuilds
TOC, fails to rebuild bibliography, and somehow manages to overwrite math 
formula
tags and contents with mostly zero-bytes and garbage (I also looked at the saved
document) - ergo there should be some kind of memory corruption.
