Hi:
I am encountering a very obscure bug in my code that does not seem to
make any sense. The basic issue is that when I send any message to an
object (in code or via command line in GDB) then I get a EXC_BAD_ACCESS
signal inside of objc_msgSend. However, I can inspect the object's
memory and all of its ivars are intact and can be accessed directly.
The problem occurs sporadically, which made me think that this would be
some kind of memory corruption issue. However, I have posed NSObject
to disable all deallocs, so I know the memory is valid. Additionally,
I can inspect the memory and everything looks to be in order.
Has anyone seen anything like this before? If not, does anyone have
any suggestions on what I can do to further diagnose this issue?
We have reproduced this bug on Panther 7B68 and 7B74 running on several
different G4 machines (dual, single, and a powerbook.)
Thanks!
-Charles
