            Bug ID: 112692
           Summary: LSAN is not compatiable with qemu user
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Keywords: testsuite-fail
          Severity: normal
          Priority: P3
         Component: sanitizer
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pinskia at gcc dot gnu.org
                CC: dodji at gcc dot gnu.org, dvyukov at gcc dot gnu.org,
                    jakub at gcc dot gnu.org, kcc at gcc dot gnu.org, marxin at gcc dot gnu.org
  Target Milestone: ---

For an example:
```
spawn qemu-aarch64 ./pr79196.exe
==1949451==LeakSanitizer has encountered a fatal error.
==1949451==HINT: For debugging, try setting environment variable
LSAN_OPTIONS=verbosity=1:log_threads=1
==1949451==HINT: LeakSanitizer does not work under ptrace (strace, gdb, etc)
FAIL: gcc.dg/asan/pr79196.c   -O0  execution test

```

Would be useful not to cause a fatal error like this while running on qemu
user.

This is the failure left from what I sent out back in 2020:

The coloring issue I mentioned there has since been fixed, I have not looked
into why though.
