Re: [Texmacs-dev] GCC-3.2 segfault debugging update

[Igor V. Kovalenko]

Hi!

Sorry I might have missed some important discussion on this subject.

This time I tried TeXmacs version 1.0.1.16 built with

./configure  -v --prefix=/home/garrison/local --enable-optimize \
                --enable-debug --enable-fastalloc=yes

and seen the following results:

gcc (GCC) 3.2.3 20030502 (actually the latest CVS from 3.2 series)
  Seems to be the same crashing thing
  (as about Nov, 2002 for TeXmacs 1.0.0.21)

gcc (GCC) 3.3.1 20030705 (prerelease) (also from gcc-3_3-branch CVS)
  Seems stable!
  Also tried --enable-fastalloc=no, seen some decrease in performance
  (as expected :) and still no crash for the same Help->Welcome test.

Any volunteer to confirm? If updated GCC fixes the stability problem
than it may be extremelly hard to determine the exact cause of failure
with 3.2 GCC.

BTW I used TeXmacs-1.0.1.16-src.tar.gz from Jun 30, 2003
with Guile 1.6.4 on latest Gentoo Linux.

Two minor compile fixes were needed:
