           Summary: gcc.target/i386/pr106010-7b.c FAILs
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---
            Target: i?86-pc-solaris2.11, amd64-pc-solaris2.11

The gcc.target/i386/pr106010-7b.c test FAILs on Solaris/x86 (32 and 64-bit)
since 20230426:

FAIL: gcc.target/i386/pr106010-7b.c execution test=20=20

The test aborts, which only happens at -g3 -O0:

Thread 2 received signal SIGABRT, Aborted.

I've found that removing all but the ps_* and epi8_* tests still lets the t=
est
abort; once you also remove the epi8_* tests, the abort is gone.=
