linux handler doesn't have sigcontext if called from a previous signal handler #182

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Since the sigcontext is a "hidden" second param, most signal handlers won't
pass it along to the next signal handler.  I have a patch that will walk
the stack back, comparing the previous ebp value to the sigcontext->ebp
value to verify that it's a good sigcontext.

This works for me in Mozilla, where we do actually get called by a previous 
signal
handler.
