Qt Creator actually looks into what you Qt does by default, and then only passes CONFIG+=release or CONFIG+=debug if needed. The most reliable way to find out if you do a release or debug build is to look for -g options on your gcc command lines. >>>> […] >>>> Try adding "QT=" to your project. >>>> >>> >>> >>> Didn't help.

Did you manually override compiler flags, or touch the mkspecs? The presence or absence of -O flags can also result in different code size, though I'd guess not in the magnitude that you experience?
