           Summary: multiple template function definitions
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: collar@gamic.com

Greetings,

I'm having a problem with gcc 3.3 that doesn't occur with gcc 3.2. The problem
relates to template functions and template specializations. If I specialize a
template function in a header file, include and use these functions in two
different implementation files, then link them all together in one library, I
get the following error from gcc 3.3:

i.o: In function `DataValidPolicy<int>::thValue()':
i.o(.text+0x0): multiple definition of `DataValidPolicy<int>::thValue()'
h.o(.text+0x0): first defined here
i.o: In function `DataValidPolicy<int>::notScanValue()':
i.o(.text+0xa): multiple definition of `DataValidPolicy<int>::notScanValue()'
h.o(.text+0xa): first defined here

I do not receive such errors from gcc3.2, gcc2.95, or Intel's icc 7 compiler.

Output from gcc3.3 -v:

I will include a testcase after I commit this entry. If you change $(CXX) to be
gcc3.2, all is well. But if $(CXX) is gcc3.3, all is broken.
