--------------------------------------
Summary: Add -fno-omit-frame-pointer to improve debugging and
profiling.
Key: MESOS-8908
URL: https://issues.apache.org/jira/browse/MESOS-8908
Project: Mesos
Issue Type: Improvement
Components: build, libprocess, stout
Reporter: Benjamin Mahler
Currently, we build without {{-fno-omit-frame-pointer}} which is needed to get
reliable stack traces. Without this, obtaining {{perf}} profiles from users is
not reliable:

Apparently, the performance win from frame pointer omission is very minor and
many projects opt to disable the optimization given the benefits to debugging
and profiling.
I tried the {{--call-graph dwarf}} "workaround" for perf but still experienced
{{[unknown]}} stack frames and what looked to be missing frames:
