[Digikam-devel] Re: macosx - macport - crash when i lauch icon view context menu

Tue Nov 2 08:16:05 GMT 2010

The malloc line (digikam(6056,0x11bc99000) malloc: *** error for object
0x3f800000: pointer being freed was not allocated) seems like a low-level
crash, furthermore you can see from the backtrace, that it crashes
in QMutexPrivate::wakeUp () and two lines up you can
see semaphore_signal_trap(), so I guess, that there is something wrong with
Qt and handling threads on mac.
