C++ Bomb.
Not much else to say for this one.  This is the standard UPX and UCL code at http://upx.tsx.org. If you want to do specific things, drop me an 
e-mail and I will give it a go...

Comment 1 Jakub Jelinek 2001-01-23 09:52:54 UTC

Can you please run
gcc  -DWITH_UCL '-DUPX_CONFIG_H="config_h/linux.h"' -I. -I/usr/src/u/ucl-0.92/include -Werror -O6 -mpentiumpro -march=pentiumpro
-march=i386 -mcpu=pentium -Wsynth -fconserve-space -fno-exceptions -fno-rtti -o c_init.o -c c_init.cpp -save-temps -v
and attach here c_init.ii this generates. ICEs are often dependant on the exact
content of all the headers which come into the game and preprocessing the source
is the easiest way how to make sure we're looking at the same thing.

Alright, file generated.  But due to the fact I dont see any way to attach a file here (I may be blind and its sitting right in front of my face), I threw it up on 
my web server, URL is as follows.

Comment 3 Jakub Jelinek 2001-01-28 15:02:21 UTC

I've commited a fix for this to CVS gcc and the patch will appear
in gcc-c++-2.96-73.
See http://gcc.gnu.org/ml/gcc-patches/2001-01/msg02070.html

Comment 4 Jakub Jelinek 2001-02-05 21:05:17 UTC

Fix is in 2.96-73 and above (currently -74).
