BUG: Calling cosl(PI/2) in a DLL May Cause GPF PSS ID Number: Q117322 Article last modified on 11-22-1994 PSS database name: VISUALC

1.00 1.50 MS-DOS

= SYMPTOMS =

Calling the run-time function “cosl” with an argument equal to one-half the value of pi (3.14159…) may generate a general protection fault (GPF) when it is called within a DLL, and when you are running it on a computer without a math coprocessor. This error does not occur when cosl is called within an .EXE file; also, it does not occur when cosl is called within a DLL or .EXE when you are running on a computer with a math coprocessor.

= STATUS =

Microsoft has confirmed this to be a bug with Microsoft Visual C++ for Windows, versions 1.0 and 1.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
