Description

[Nathan Froyd [:froydnj]]

Discovered this on the Mac today, latest m-c code.  I wind up with crashes like:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0xffffffffffffffd8
0x00007fff8f1a22b2 in libunwind::CompactUnwinder_x86_64<libunwind::LocalAddressSpace>::stepWithCompactEncodingRBPFrame ()

That's on an opt build, going to go have a look at a debug build to see if the stacks are any better.

Is this still happening? If so, is it a dup of bug 995443?
