Title:
qemu-system-arm Crashes on startup on OS X 10.8.2
Status in QEMU:
Invalid
Bug description:
On startup qemu-system-arm crashes on this line 9373 of target-arm
if (unlikely(!QTAILQ_EMPTY(&env->breakpoints))) {
QTAILQ_FOREACH(bp, &env->breakpoints, entry) {
if (bp->pc == dc->pc) { // <-- CRASH !!!!
gen_exception_insn(dc, 0, EXCP_DEBUG);
/* Advance PC so that clearing the breakpoint will
invalidate this TB. */
dc->pc += 2;
goto done_generating;
break;
}
}
What appears to be happening is env is
(gdb) print env->breakpoints
$4 = {
tqh_first = 0x1f001f001f001f,
tqh_last = 0x1f001f001f001f
}
which leads to bp being set to
(gdb) print bp
$1 = (CPUBreakpoint *) 0x1f001f001f001f
This looks like a bad address and causes the following statement
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: 13 at address: 0x0000000000000000
I am wondering if the env structure is not getting setup correctly?
