Bug ID: 16276
Summary: ASAN: Forward real abort(3) once done handling errors
and printing the stack
Product: compiler-rt
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: compiler-rt
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
On darwin, processes spawned by launchd (launch daemons or agents) that crash
will trigger ReportCrash. This will drop a crash log on the filesystem which
can be automatically symbolicated.
Unfortunately, it looks like programs linked with ASAN won't forward an abort
signal to the operating system, exiting 1 instead. launchd won't trigger crash
reports when processes exit normally with a return code.
Is there some way we can uninstall the signal handler and/or forward an abort
somehow?
Steps to reproduce:
- Create a test C program that triggers an ASAN memcpy range overlap error.
- Run it
Results:
Process returns 1.
