Yes, it does only crash in the debugger. Data formatters could be a
prime suspect because I am getting an alert displayed at every
breakpoint telling me that the debugger can't load the CF and Carbon
data formatters. I wasn't aware that there was an option for turning
them off so I'll try that - I won't lode anything because in all the
time I've been using XCode I've never seen any data formatter
actually work.
Thanks,
Jerry

when you either use Xcode's "Run Executable" or run it from Finder
or Terminal?
If the answer to that is yes, then the first thing to try is
turning off the data formatters, and see if they are causing the
problem. To do this, uncheck Debug->Variables View->Enable Data
Formatters. They do end up running code in your app, which is
usually benign, but may cause problems.
You've probably already done this, but just in case, make sure
you've cleaned ALL the targets in your project, and any other
projects you may be relying on, and rebuild.

Since upgrading to Tiger/Xcode 2, I've been plagued with constant
crashes of my app when debugging, making it almost impossible to
use the debugger at all. Almost any attempt to single step, step
in or out, results in an EXC_BAD_ACCESS with a stack trace that
has nothing to do with where I was. For example, today, stepping
over a line which says something like x = 1 causes a crash in
TIFFRegisterCodec. Also, I get get constant crashes in getenv,
which appears to be called from a variety of system functions.
Calling getenv from the gdb console command line results in the
same crash.
Any ideas? This was a upgrade install of Tiger from 10.3.9 (no
Tiger seeds have contaminated this machine). I've tried
reinstalling Xcode Tools twice to no effect, fixing permissions
etc. etc.. I'm using gcc 3.3.
