_NSZombie Breakpoints won't Resolve (Xcode 3.2.2)

I'm attempting to debug an autorelease issue using NSZombie.  I've done this several times before and it worked.  Today, however, my NSZombie breakpoints look like they are never resolved and thus never break.  For example:

When I check the box, it turns back to a dash after a second.  According to the "Xcode Debugging Guide",

"A dash in this checkbox indicates that, while the breakpoint is turned on, the debugger has not yet resolved it. When you start debugging, these dashes change to checkmarks as the debugger resolves each breakpoint."

Well, when I start debugging with NSZombieEnabled and NSAutoreleaseFreedObjectCheckEnabled, these dashes do *not* change to checkmarks, and consequently my program blows right by the point where it crashed when NSZombieEnabled and NSAutoreleaseFreedObjectCheckEnabled were not enabled.

I am using Xcode 3.2.2, and most of the project code is in a private framework.  However I am aware of the bug in Xcode 3.2.2 which causes it to blow by breakpoints in such frameworks, and am using the workaround of trashing the built frameworks before running.  Thus my other breakpoints, those with checkmarks that stick, break as expected.

What might be wrong with _NSZombie today?
