SYMPTOMS
Compiling an application that uses a local temporary static union, as does the sample code shown in the More Information section below, may cause the following internal compiler error when built with debug information only:

TEST.CPP(9) : fatal error C1001: INTERNAL COMPILER ERROR

(compiler file 'e:\b_bld\c2\P2\main.c', line 374)

Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information

TEST.CPP is the sample code file given in the More Information section below.



RESOLUTION
Use either of these two workarounds:

 Remove the /Zi compiler option. -or-

  Create an object to represent the local static union: static union { int z;} tmp; 



STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This problem was fixed in Visual C++, 32-bit Edition, version 4.0.



Sample Code
/* Compile options needed: /Zi

static union { int i; }; static union { int k; };

void local {  union { int x; }; union { int y; }; static union { int z; }; }
