It also fails much earlier when I enable logs with "-d int -D log".
Here is backtrace for this failure:

Subject: qemu-2.8-rc4 is broken
Hi!
I encountered the following bug with the latest version of QEMU.
I use windows host and start qemu with the following command line:
qemu-system-i386.exe -soundhw ac97 -snapshot -hda disk.qcow2 -net none
Guest system is Windows XP 32-bit. It founds new hardware (including audio
controller)
and I start playing mp3 file.
After seconds of playing qemu fails with an exception.
I tried to bisect between 2.7 and 2.8, but bug is not stable.
It manifested itself at commits "68701de1362b29fd6941a2021e9393ddbe60edd8" and
"6a928d25b6d8bc3729c3d28326c6db13b9481059".
