I am seeing the same think when I try to run a sample built under gcc
from the TI tools
117 void qemu_iohandler_poll(fd_set *readfds, fd_set *writefds, fd_set
*xfds, int ret)
118 {
119 if (ret > 0) {
120 IOHandlerRecord *pioh, *ioh;
121
122 QLIST_FOREACH_SAFE(ioh, &io_handlers, next, pioh) {
(gdb) l
123 if (!ioh->deleted && ioh->fd_read && FD_ISSET(ioh->fd,
readfds)) {
124 ioh->fd_read(ioh->opaque);
125 }
(gdb) print ioh
$2 = (IOHandlerRecord *) 0x5
However Peter Maydell sent me a kernel image that runs fine on OS X.
However when I try to run it under gdb I get the same problem that you
see.

Status in QEMU:

Bug description:
I have an issue when I try to run qemu-system-arm on Mac OS X.
Sometime between 1 and 15 secs after qemu is started it crashes
as shown bellow.
Same thing on linux host works fine.
Is anybody else experiencing this?
Any Hints?
Thanks,
Damjan
