Windows loads AcGenral.dll when the application is loaded (the documentation is sparse, it says it's used for application compatibility). When application tries to call msvcrt!_control87 a code inside AcGenral.dll is called instead. The implementation inside AcGenral is not setting x87 nor sse control word in case of _control87(0x100, 0x300) call. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
