Thanks that helped, but did not immediately fix the problem.
First I tried setting DYLD_IMAGE_SUFFIX=_debug in .profile, but XCode
ignores this.
I discovered that in Xcode 4.5 you can select Product -> Edit Scheme,
click the Arguments tab and add 'Environment Variables'
I added DYLD_IMAGE_SUFFIX=_debug.
But that still didn't work. The final step was to click the Info tab in
the Edit Scheme
dialog, and change the Debugger to GDB.
I can now step into Qt code, and it has already helped me fix a subtle
bug in my code!
Thanks for your help.
John.
