            Bug ID: 32407
           Summary: [gdb/testsuite] SIGILL in gdb.base/valgrind-*.exp
                    test-cases
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal

  Target Milestone: ---

On i586, I'm running into a SIGILL which causes a FAIL:
...
(gdb) continue^M

This is with leap 15.5 and 15.6, doesn't trigger with tumbleweed.

Likely a problem in valgrind that has been fixed in a newer version.

Doesn't look like there's anything wrong with gdb, so no FAILs should be
produced.

Likewise in all other valgrind test-cases.
