Subject: c++/3671: g++ incorrectly tries to instantiate multiple member template specializations
Date: Fri, 13 Jul 2001 03:26:00 -0000 [thread overview]
Message-ID: <20010713102109.8039.qmail@sourceware.cygnus.com> (raw)
>Number: 3671

>Description:
g++ emits the following error message when compiling my test program:
Dependent_Types_Specialization.cpp: In function `int main()':
Dependent_Types_Specialization.cpp:79: cannot convert `Index2' to `Index1' in
initialization
Dependent_Types_Specialization.cpp:79: non-constant `<expression error>' cannot
be used as template argument
The problems seems to be that g++ incorrectly tries to instantiate both versions of the get_index member template in the class template Compound_Type. Therefore the index_type given at the instantiation place in the main program will not match one version and trigger the error message.
The program compiles without problems using the EGD frontend 2.44.
>How-To-Repeat:
run g++ on the file Dependent_Types_Specialization.cpp, no special flags are needed
>Fix:
don't know one!
