DOCUMENT:Q155386 04-AUG-2001 [visualc] TITLE :FIX: C1001 in Compiler File MSC1.CPP at Line 1089 PRODUCT :Microsoft C Compiler PROD/VER:4.2 OPER/SYS: KEYWORDS:kbCompiler kbCPPonly kbVC kbVC500fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - The C/C++ Compiler (CL.EXE), included with: - Microsoft Visual C++, 32-bit Enterprise Edition, version 4.2 - Microsoft Visual C++, 32-bit Professional Edition, version 4.2 ------------------------------------------------------------------------------- SYMPTOMS ======== When defining a template function and a nontemplate function of the same name such that the nontemplate version is defined within a namespace, you may encounter the following error: test.cpp(28) : fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'msc1.cpp', line 1089) RESOLUTION ========== There are three ways to work around this problem: 1. Change the name of one of the functions involved. -or- 2. Move the using directive to local function scope. See the sample code below. -or- 3. Instead of a using directive, use the scope resolution operator to reference objects in the namespace. See the sample code below. 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 Visual C++ version 5.0. MORE INFORMATION ================ Sample Code ----------- /* Compile options needed: None */ template int test1( T x) { return 1; } namespace A{ int test1(int) { return 1; }; } int test2() { return test1(1); } using namespace A; // comment out this line for workarounds 2 & 3. void main() { // using namespace A; // uncomment this line for workaround 2 test1(1); // A::test1(1); // uncomment this line for workaround 3 } Additional query words: kbVC420bug ====================================================================== Keywords : kbCompiler kbCPPonly kbVC kbVC500fix Technology : kbVCsearch kbAudDeveloper kbCVCComp Version : 4.2 Issue type : kbbug Solution Type : kbfix ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
