Catch SIGABRT on Mac? #343

Closed GoogleCodeExporter closed 9 years ago

An assertion in the C++ standard library is calling abort(), which results
in SIGABRT.  At least in 10.6, Crash Reporter is picking these up as EXC_CRASH.

EXC_CRASH is generated differently from the other exception types, and trying 
to 
intercept it gets things really angry.  EXC_CRASH comes from the kernel in 
response to 
certain sorts of abnormal process terminations (like, apparently, SIGABRT-based 
abort).  
It appears that it would be more proper in this case for the handler to catch 
(and 
possibly re-raise) SIGABRT than to try to catch the Mach exception.  I don't 
think we 
actually want to catch EXC_CRASH.

This causes Breakpad to miss some types of crashes in C++ programs.  Stack 
buffer overflow checks and pure virtual function calls both crash using abort().

I started working on this a while ago but didn't finish it. The iOS port added 
code for this, but it needs to be fleshed out for x86.
