I doubt it. That patched enabled more functions to be compiled that weren't being compiled before, but didn't fuss with anything lower level.

Setting needinfo from Brian since this involves the backtracking allocator.

This doesn't reproduce for me on x86 or x64.
By the testcase, it looks like it was probably hitting bug 900437, however I don't see a failure even when I disable the fix for that bug, so possibly something else has changed besides.

Also didn't reproduce for me anymore, marking as WFM unless it pops up again or does reproduce for someone else.
