The log file path "/crtc.log" is invalid letting the initial fopen() fail, returning NULL FILE*. The call to fprintf() is done with NULL FILE*/crtclog resulting in garbage pointer offset (while trying to lock FILE).
It is very likely that this app crashes in Windows too - because of that invalid log file path - making the bug invalid. Someone should verify by running the app from download link on Windows machine.

Well, the path is seriously questionable, but Windows does happily create the log file, presumably by interpreting it relative to the current working drive. The real problem is that Wine interprets the path as a Unix path and tries to create the file in the root directory of the filesystem, as the last error of CreateFile suggests. I think there's an open bug for this somewhere.
