FIX: Fatal Error C1001 'd:\b_bld\c2.m2\P2\main.c', line 374

The information in this article applies to:

• The Microsoft C/C++ Compiler (CL.EXE) included with: Microsoft Visual C++, 32-bit Edition, versions 2.0 and 2.1

SYMPTOMS

An attempt to compile code that defines the exception handling mechanism in a function that takes a class argument by value, causes the compiler to generate the following error message:

   bug.cxx(19) : fatal error C1001: INTERNAL COMPILER ERROR
   (compiler file 'd:\b_bld\c2.m2\P2\main.c', line 374)

RESOLUTION

Pass class A by reference instead of by value in the Func call in the sample code in this article.

STATUS

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