New issue 331 by decoder...@googlemail.com: Problem with opendir / fstatfs
in Firefox on Mac OSX
http://code.google.com/p/address-sanitizer/issues/detail?id=331
I briefly talked to kcc about this issue and he suggested to file a bug,
even if the bug might be in our code. I'm trying to run Firefox with ASan
on Mac OSX now and I'm hitting this bug constantly on startup:
https://bugzilla.mozilla.org/show_bug.cgi?id=935795
There are multiple things that could be going wrong, like us bypassing an
interceptor (we've had that before for certain calls to free), a missing
interceptor, or just a regular bug that can't be seen from the stack. The
bug is certainly OSX only, we haven't hit such a problem on Linux before.
Since this is a blocker for us, I'm happy for any debugging suggestions or
patches to try :)
kcc also mentioned: " The report looks broken. First, the stack is short --
for some reason we failed to unwind it fully. Second, it sounds weird --
why would opendir touch so many local variables. Does this code perform any
kind of stack unwinding (similar to throwing exception or longjmp)? "
I am not aware that we have any form of custom unwinding involved here, but
I could be wrong :)
