Using qemu master rev dbd99ae..25bbf61 configured with:
./configure --disable-sdl --disable-kvm --enable-cocoa --enable-debug
--extra-cflags=-g --extra-ldflags=-g
(I'm using clang 4.1 now. Should I be using clang or gcc 4.2? Are these
the right config args?)

Title:
crash at qemu_iohandler_poll (iohandler.c:124) on macos 10.8.2
Status in QEMU:
New
Bug description:
I'm seeing consistent hangs / crashes on MacOS 10.8.2 with 1.3.0.
I've tried both gcc-4.2 and clang. I've tried a half a dozen
different images/kernels.
I configured qemu like this:
./configure --disable-sdl --disable-kvm --enable-cocoa --cc=gcc-4.2
--host-cc=gcc-4.2 --enable-debug --extra-cflags=-g --extra-
ldflags=-g
And ran it like this:
qemu-system-arm -nographic -M versatilepb -kernel
vmlinuz-2.6.32-5-versatile -initrd initrd.img-2.6.32-5-versatile -hda
debian_squeeze_armel_standard.qcow2 -append "root=/dev/sda1
console=ttyAMA0"
With images, kernel, and initrd described here:
http://psellos.com/2012/08/2012.08.qemu-arm-osx.html
And I get:
