--- Comment #10 from Rafał Mużyło galtgendo@o2.pl --- If someone here has an idea for a minor code change that would help to narrow down the problem more than the last log does, I'm open for reasonable suggestions. Though given that it's a stack corruption and by gdb output seems to happen in wineserver, this might be tricky - my debugger skills are quite low, likely insufficient for chasing down a locking problem. (only idea that comes to me would be a TRACE on locking/unlocking gdi_lock, but that seems too noisy)
Also, that aquafont/aquapfont pair in the log are sometimes quite nasty neighbors (for example, one of them tends to get picked in a chromium based browser (without any good reason) on some of the pages, making them very difficult to read (especially if you don't really know the language in the first place)), but fortunately in wine apps seems to be ignored.
