Re: [Qemu-devel] [Bug 1588328] Re: Qemu 2.6 Solaris 9 Sparc Segmentation Fault

[Artyom Tarasenko]

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.
