SUMMARY

when we try to attach to a SIGSTOP'ed process, then GDB attaching fails

STEPS TO REPRODUCE
1. start app
2. ctrl+z to stop
3. attach heaptrack

OBSERVED RESULT

heaptrack output will be written to "/home/milian/projects/build/heaptrack/heaptrack.threaded.88898.zst"
injecting heaptrack into application via GDB, this might take some time...
The program received a signal in another thread while
making a function call from GDB.
Evaluation of the expression containing the function
(malloc) will be abandoned.
When the function is done executing, GDB will silently stop.
No symbol "heaptrack_inject" in current context.
injection finished


EXPECTED RESULT

it works
