--- Comment #5 from Theodore Bumpers wine@londonlight.org --- Fabian the crash is not the bug, the crash is a result of the bug. The bug here is that FormatCurrency in wine formats "9" as ".9.00", with two period characters. Reproduced by multiple people on different machines using different locales. In Windows, FormatCurrency(9) would return for example "9.00 BTC".
I'm happy to provide you with any info you need, just instruct me how, as I'm somewhat familiar with GNU GDB but not with winegdb or wine's "debug channels".
