sa_mask is not initialised in linux exception_handler.cc #288

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
sa_mask should probably be initialised before calling sigaction

I was going to file this bug for chrome but then I realised that breakpad
is a separate project ... I spotted this by running the chrome test_shell
under valgrind btw.

The change is here:

http://codereview.chromium.org/13653/show

but I'm not claiming that's 100% correct. In particular:

1. I'm not sure if any signals should actually be blocked during the signal
setup, and
2. Recompiling chrome with this fix works but for some inexplicable reason,
valgrind still claims act->sa_mask is uninitialised. I haven't dug into
that in detail.

Comments please!

Thank you

dupe of issue 242 (which also has a patch that sadly never got checked in).
