The source of the binary is (compiled on Visual Studio 6.0, with option \MT and _MT and _DLL defined) see https://msdn.microsoft.com/en-us/library/aa272081(v=vs.60).aspx #include <strstrea.h> int main() { ostrstream oss; return 0; } The Visual Studio project, binary and console output are bundled in the attached tar. The error is: wine: Unhandled page fault on write access to 0x00000000 at address 0x405000 (thread 000 9), starting debugger... Unhandled exception: page fault on write access to 0x00000000 in 32-bit code (0x00405000 ). In current git all functions called in mscvirt are stubs. I believe that this should not cause a null pointer access. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
