gcc oopses with 2.4.3

[Norbert Preining <preining@logic.at>]

Hi!

I get frequent `internal compiler error', killed with Sig 4  or Sig 11
and sometimes Ooops from compiling X or kernel. 

System: 2.4.3-vanilla, reiserfs, glibc-2.1.3
[~] gcc -v
Reading specs from /usr/lib/gcc-lib/i486-suse-linux/2.95.2/specs
gcc version 2.95.2 19991024 (release)


Here a decoded Ooops:

ksymoops 0.7c on i586 2.4.3.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.3/ (default)
     -m /boot/System.map-2.4.3 (specified)

I hope it helps a bit, but it doesn't look like ;-)

Please Cc: me any answers, thanks!
