Hi,

just out of interest: which Mac version do you use? Because we're aware 
of an issue in Snow Leopard that let the program crash as soon as you 
use DYLD_IMAGE_SUFFIX=_debug, and have also an report that it 'doesn't 
work' on latest Mac OS X Leopard.

I somewhat doubt it that this is possible with qmake, but you never know 
... ;) Anyhow, since it's an environment variable you might be able to 
set it globally, e.g. in ~/.MacOSX/environment.plist . Haven't tried 
this myself though.
