BUG: Internal Compiler Error, C1001, MSC2.CPP, line 1011 |
Q114532
The information in this article applies to:
- The C/C++ Compiler (CL.EXE), included with:
- Microsoft Visual C++, versions 1.5, 1.51, 1.52
SYMPTOMS
When using the /Ol switch (enable loop optimizations) and compiling a module that contains several large loops, or that contains several layers of nested loops, version 8.0c of the Microsoft C/C++ compiler may generate the following error message:
file.c(xxx) : fatal error C1001: internal compiler error (compiler file 'msc2.cpp', line 1011)
RESOLUTION
There are two workarounds for this error message:
- Compile using the fast compiler. Use of the fast compiler can be forced by using the /f compiler switch.
Do not compile with loop optimizations enabled. This can be done either at the module level by removing the /Ol option from the compiler command line, or at the function level by using #pragma optimize directives. The syntax of the #pragma optimize directive is as follows:
#pragma optimize( "l", off ) // Disable loop optimizations // Function that contains the code causing the problem. // This can be determined by the line number given in the // C1001 error message. #pragma optimize( "l", on ) // Enable loop optimizations
STATUS
Microsoft has confirmed this to be a problem with the C/C++ compiler version 8.0c. We are researching the problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
