SIGSEGV triggered by `tracing_exception_span_create`

Question

SIGSEGV triggered by `tracing_exception_span_create`

RichardHeelin opened this issue 6 years ago · 1 comments

We noticed that some of our backend processes started to error with segmentation faults. Upon digging into the core dumps we found that the issue seems to be related to calls to tracing_exception_span_create when nested inside multiple calls to tideways_execute_ex.

We have so far not been able to reproduce in a simple test case, but can always reproduce with our full stack when a php fatal is hit due to a missing function.

For reference the core dump bt:
