            Bug ID: 115575
           Summary: experimental/simd/pr115454_find_last_set.cc FAILs
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++

  Target Milestone: ---
            Target: sparc-sun-solaris2.11

The new experimental/simd/pr115454_find_last_set.cc test FAILs on 32 and 64=
-bit
Solaris/SPARC:

FAIL: experimental/simd/pr115454_find_last_set.cc -mcpu=3Dultrasparc -mvis =
-O2
-Wno-psabi execution test

This happens even when compiling with -g3 -O0.  The test aborts:

Thread 2 received signal SIGABRT, Aborted.
