SYMPTOMS

When you use an incomplete #pragma preprocessor directive, the following internal compiler error may be generated:

warning C4081: expected '('; found 'newline'
fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 899)
Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information.

While the code is not valid, the compiler should not generate an internal compiler error. However, the C4081 warning is valid.
