BUG: CVW 3.x and FORTRAN DLLs: Stack Trace Hangs Machine (85164)
The information in this article applies to:
- Microsoft FORTRAN Compiler for MS-DOS 5.1
- Microsoft FORTRAN compiler for OS/2 5.1
This article was previously published under Q85164 SYMPTOMS
Using Microsoft Codeview for Windows versions 3.x under Windows 3.1 to
debug Microsoft FORTRAN 5.1 Windows DLLs that have been called by C
applications can hang the machine if the CALL menu is selected or the stack
trace command, K, is entered in the command window.
CAUSE
There is a problem in the CodeView for Windows FORTRAN expression
evaluator that is incorrectly accessing the stack.
RESOLUTION
If a stack trace is desired, enter the command
in the command window. This will cause CVW to use the C expression
evaluator. To return using the FORTRAN expression evaluator type
in the command window.
STATUS
Microsoft has confirmed this to be a problem in FORTRAN version 5.1.
This is not an issue in FORTRAN PowerStation.
MORE INFORMATION
To duplicate this problem, build the MULMIX_D project that is provided in
the FORTRAN 5.1 samples subdirectory. There is a makefile that is provided
called MULMIX_D.MAK. The makefile assumes that C 6.0 will be used. Using
C/C++ 7.0 to build the application and DLL avoids the problem because there
is no FORTRAN expression evaluator for the 4.0 versions of CV or CVW which
are provided with C/C++ 7.0.
