Recompiling QT with debug unfortunately makes the problem go away. Similarly 
recompiling with -O2 instead of -O3 did the trick. It looks to me as if it's 
triggered by the optimisation level. Not sure whether TT advise not to use 
-O3. Thanks for the advice - at least I'm now more sure it's not caused by 
*my* code :-)
