>Environment:
Linux 2.4.16, glibc 2.2.4
>Description:
When compiling the program john the ripper with the maximun optimization options, gcc can not compile the compiler.c module, and I have to reduce the optimizations options.
The compiler crashes.
I know I'm using a still developing feature, so this is a file to test it and fix the crash.
>How-To-Repeat:
gcc -c -Wall -O2 -fomit-frame-pointer -march=i686 -O3 -fpeephole2 -fsched-spec -fsched-interblock -fssa -fdce -funroll-all-loops -fschedule-insns2 -fdelayed-branch -fthread-jumps -fdelete-null-pointer-checks -frerun-loop-opt -funroll-loops compiler.c -save-temp
gcc: unrecognized option `-save-temp'
cc1: warning: this target machine does not have delayed branches
compiler.c: In function `c_direct':
compiler.c:1131: Internal error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
>Fix:
Remove the -fssa from the command line options.
