That's it.  Even when the build configuration is set to debug, it was
still compiling in release mode.

Turns out in my .pro file (which came from pre-QtCreator days), I had
put in a CONFIG += release, so that's what was causing the problem.
Removing that line solves everything.

So the problem was a change in behaviour between QtCreator versions.
In 1.0, specifying Debug mode in the build configuration overrides
whatever is in the CONFIG in the pro file, in QtCreator 1.1, the pro
file overrides the build configuration setting.  I don't know what is
more correct, but it is certainly confusing to set Debug and end up
with a release build.
