Thanks for the bug report. The backtrace has no symbol information so it is
hard to tell where in QEMU goes wrong.

Please ./configure --enable-debug or install the debuginfo package that comes
with your qemu package. This will add symbol information to the backtrace when
you reproduce the buffer overflow again.
