I ran into the same problem with -O1 (tested from a fresh checkout).
Did you ever find any way out?
Looks like -O0 does the trick for me.

Weirdly enough, I'm 99% sure I had tested this with -O1 and it was 
working fine. But maybe I was then starting with a *NOT* clean 
environment (first compiled something with -O2 and then switched 
afterwards).
Whatever.

Thanks,
