Dear list,
I've been trying to track down a crash that happens sometimes when a document
is closed in my NSPersistentDocument based app. This started to appear during
the process of going from GC to non-GC. But it only happens after an
undetermined number of document closes and reopens. The error message I get in
the debugger is
* thread #1: tid = 0x2103, 0x00007fff8f614e90 libobjc.A.dylib`objc_msgSend +
16, stop reason = EXC_BAD_ACCESS (code=1, address=0x10)

frame #7: 0x0000000100001574 TeXnicle`start + 52
I've tried disabling various parts of the app trying to isolate where the issue
might be.
Could anyone offer any advice on how I might better track this down? Perhaps
using instruments in some way?
Cheers,
Martin
