BUG: Illegal Formal Argument and -Zi Crash CompilerLast reviewed: July 13, 1995Article ID: Q112005 |
The information in this article applies to:
- Microsoft FORTRAN PowerStation for MS-DOS, versions 1.0 and 1.0a - Microsoft FORTRAN PowerStation for Windows NT, version 1.0
SYMPTOMSUsing FORTRAN PowerStation to compile a file that contains a subprogram using a formal argument that has the same name as that subprogram may produce the following errors under Windows NT:
error F2209: (variable_name) : illegal as formal argument fatal error C1900: Il mismatch between 'P1' version '0' and 'P2' version '19930414'These error messages are then followed by a stack overflow exception. When using FORTRAN PowerStation for MS-DOS, the F2209 error is generated. If compiling from the Visual Workbench, the following errors also occur:
error F2513: (variable_name) : not a variable error F2530: (variable_name) : symbol class illegal here error F2040: label on continuation line error F2037: illegal label fieldThe F2040 and F2037 errors scroll repeatedly showing negative line numbers, until finally the compiler crashes with a DX1020 general protection (GP) fault error. The F2040 and F2037 errors do not occur if compiled from the MS-DOS command line, but the DX1020 error does. In all cases the F2209 error is correct.
CAUSEThis error occurs only when using the -Zi compiler option.
RESOLUTIONCorrect the error by renaming the formal argument. Then recompile with -Zi.
STATUSMicrosoft has confirmed this to be a problem in FORTRAN PowerStation version 1.0 and 1.0a for MS-DOS, and version 1.0 for Windows NT. Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
