So the bug has nothing to do with WideCharToMultiByte. A hint for the bug is visible in the log: "input size" is not 11. Verified with a stripped down example: * The static initialization of the wstring fails with wineg++ * Using g++ works without faulure. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

This testcase can be compiled with g++ (result works) and wineg++ (result fails) Does "-fno-short-wchar" make it any better? The underlying issue is probably that wchar_t is usually 32 bits on Linux, and 16 bits on Windows. Winegcc uses -fshort-wchar to try to work around that, but that means you can't then use things like Linux libstdc++ that assume wchar_t is 32-bit.
If you're using C++11 in particular, you're probably better of with "-fno-short-wchar" and using char16_t, u"", etc. instead of wchar_t and L"". -- 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.
