Comment 7 for bug 1588328

Can you guys check if the problem persists when qemu is launched with
the -singlestep option?
I think it's in general a good idea always check TCG-related problems
with -singlestep , because it helps to find out whether a bug is in
the optimizer or generator module of TCG.
