If I run it normally, it crashes in the same way. If I pass the signal
through it crashes in the same way. I sort of expect this, since it is
qemu segfaulting when it tries to generate the code buffer, not the
underlying problem.

Title:
SIGSEGV in static_code_gen_buffer
Status in QEMU:
New
Bug description:
Trying to run 'ls' (or, anything else as far as I can tell) from a
SunOS 5.8 box under RHEL 6.4 linux, I get a segfault. I've tried
qemu-1.5.3, qemu-1.6.0, and I fetched git://git.qemu-
project.org/qemu.git. I've also tried a statically linked sh from
/sbin/ and it also segfaulted.
