https://bugs.winehq.org/show_bug.cgi?id=42474 --- Comment #18 from Sebastian Ernst <ernst(a)pleiszenburg.de> --- I just did. In the meantime, there are two lines of code which could trigger this exact fatal error (the messages are ironically identical): https://github.com/python/cpython/blob/3.6/PC/getpathp.c#L237 https://github.com/python/cpython/blob/3.6/PC/getpathp.c#L240 If it is the latter, you might be looking at a bug in your implementation of PathCombineW (?). I do not have a tool chain up and running for re-compiling Python for Windows with a bit more verbosity at this very spot ... Maybe this would help. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
