We're trying out XCode 2.1, finally, to build some of our stuff on
Tiger and PowerPC, and immediately run into strangeness with gdb.
Admittedly much of our code is in the form of plug-ins, but we
haven't had difficulties with gdb like this with 1.5, and I did a
quick search of the XCode list archive to see if anyone else has
seen this but didn't notice anything.
All I have to do is set a breakpoint and the app stops. The message
in the debugger window is that the application exits normally, while
the console reports twice that gdb encountered a SIGBUS exception. I
can set the breakpoint before starting the debug session and gdb
will eventually exit. I can set the breakpoint after the app
successfully starts and is waiting for user interactions; gdb will
immediately exit with SIGBUS.
If I don't set a breakpoint, the app appears to run fine.
I can set the fancy watchpoint options like Sound without incident.
Odd. Is this a known issue mentioned somewhere?

Just so folks know, after playing with this problem for a while on
two different machines, moving build products around and changing
parameters, I removed XCode 2.2 dp1 from one Tiger machine using the
uninstall script and reinstalled 2.2 clean. The problem still showed
up.
Then I removed XCode 2.2 dp1 again and installed XCode 2.0 from the
Tiger install DVD. The debugger works again, the problem does not
appear.
