Hi, last time I talked with Christian, he said that he changed the code of qgpslogger, that it works OK without this optimizations.. Not sure if that change is possible also in NWA code (probably can be easily found in qgpslogger repo). But from my opinion, if there is some simple code, which can trigger this problem in reproducible way, then it whould be fixed in qt/app code (enabled optimizations are maybe hiding some nasty concurrency problem, but probably cannot fix the real problem). Maybe it will fail again (or resolve automagically )with newer gcc/qt, so I would like to see backtrace or some good explanation what happen without those flags. BTW: we have already gcc-4.4.3 instead of 4.4.2 but qt wasn't rebuilt since that change.. if someone sends me some testcase I'll try it here.
