Comment # 3 on bug 76044 from Christopher Egert

I've tried to revert this commit on master and the trace worked fine, after
reverting the revert, it crashed again. I've also tried (with and without this
commit) to build with -O0 to rule out compiler optimization bugs.

This is on Debian unstable with gcc (Debian 4.8.2-16) 4.8.2
