Just bisected a segfault for aarch64 nbench on a PowerPC host
to this commit (79d61de6bdc398). I've also tested on x86_64 and
aarch64 hosts, and these do not seem to be affected.
To reproduce:
1. grab this binary:
http://cs.columbia.edu/~cota/qemu/nbench-aarch64
2. run it on a PowerPC host with:
$ aarch64-linux-user/qemu-aarch64 nbench-aarch64 -V
Note: the "-V" (or "-v") flag is important! Without it, there's no segfault.
I can reproduce this consistently on a Power8 host -- I'm using gcc112
from the gcc compile farm.
Thanks,
Emilio
