SYMPTOMS
When you compile a file, such as the following sample, with global optimization enabled, the following error occurs:

Text1.cpp(9) : fatal error C1001: INTERNAL COMPILER ERROR

(compiler file 'E:\utc\src\\P2\main.c', line 379) Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information



RESOLUTION
Remove the global optimizations for the source file or use the optimize pragma to remove the optimization for the function which is causing the error.

NOTE 1: If you are optimizing to minimize size (/O1) or maximize speed (/O2) then global optimization (/Og) is enabled as these options consist of several optimizations which includes global optimization.

NOTE 2: The default compiler options /GZ (Catch Release-Build Errors in Debug Build) and /ZI(Program Database for "Edit and Continue") are incompatible with /Og option.



STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been fixed in Visual Studio 97 Service Pack 3.

class A { public: void Recursive(D3DVECTOR p1, D3DVECTOR p2, D3DVECTOR q1,             D3DVECTOR q2, D3DVECTOR& ret); };
 * 1) include 

void A::Recursive(D3DVECTOR p1, D3DVECTOR p2, D3DVECTOR q1,             D3DVECTOR q2, D3DVECTOR& ret) { Recursive(q1, q2, p1, p2, ret); }
