Hi,
Just in the last several days I have also experienced the same exact
problem in relation to CFBundles & CFPlugIns. It only occurs during
debugging (evident from the 'gdb' within the call stack) so it is not
too much of an issue - but could really be an issue for those who have
plug-ins unloading/loading on the fly while trying to debug.
Have you tried disabling Fix & Continue?
Regards,
Jared Watts.

Hi,
I'm writing an audio plug-in as a Mach-O bundle using Xcode 1.2. I'm
trying to figure out what's causing the following behavior:
The host calls CFBundleUnloadExecutable to unload my plugin, and then
I just get the spinning wait cursor. If I pause the debugger, the call
stack is always:
#0 0x8fe160fc in __dyld_gdb_dyld_state_changed
#1 0x8fe13538 in __dyld__dyld_unlink_module
#2 0x90205500 in _CFBundleDYLDUnloadBundle
#3 0x901ecdd8 in CFBundleUnloadExecutable
... (host-specific call stack)
The debugger console says:
Cannot remove breakpoints because program is no longer writable.
It might be running in another process.
Further execution is probably impossible.

and "step instruction" doesn't seem to move the instruction pointer.
Does this behavior sound familiar to anyone? I'm not quite sure how to
proceed in debugging it since it's unclear to me what state the
process is in when the above happens.
Thanks for any help,
Jeremy
