Hi Chris,
No, I haven't seen this before. The macro doesn't do anything different
except for the ibd events. Maybe try replacing the ibd events with a
basic gun. Also, the seg faulting at different places seems like a memory
allocation problem, and I know that these ibd events seem to take a LONG
time and a lot of memory. If you run the debugger and can shed some light
on where the code is taking a lot of time, I would really appreciate it.
