            Bug ID: 109237
           Summary: csmith: another timeout with -g -O3 this time
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

Created attachment 54722

C source code

The attached C code, when compiled by -O3, seems to take a reasonable time:

$ time ~/gcc/results/bin/gcc -c -w -O3 bug901.c

real    0m0.619s
user    0m0.597s
sys     0m0.012s

But adding -g seems to cause trouble:

$ (ulimit -t 120; time ~/gcc/results/bin/gcc -c -w -g -O3 bug901.c)
gcc: fatal error: Killed signal terminated program cc1
compilation terminated.

real    2m1.255s
user    1m58.650s
sys     0m1.593s

$ ~/gcc/results/bin/gcc -v 2>&1 | fgrep exp
gcc version 13.0.1 20230321 (experimental) (0963cb5fde158cce) 

So the version I used seems to include today's patch from Andrew Macleod
for timing reduction.
