Going off on a tangent here, but...

Qt has release mode, debug mode and the "-developer-mode" switch. Be careful 
not to confuse the latter two: developer mode is debug mode but enables a few 
extra things so Qt's own unit tests can run, like exporting some functions so 
they can be called from the tests. Another consequence is that it compiles 
with -Werror and compiles each header individually, so the build time 
increases and you're more likely to get build failures.

Unless you're developing Qt itself like me, you don't want that option. Debug 
mode is fine for debugging into Qt itself and enables Q_ASSERT.
