           Summary: [REGRESSION] incorrect warning of missing return
                    statement
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: merkert at charter dot net
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: g++ (GCC) 3.4 20031001 (experimental)

The following code prints a warning:

cat > test.cpp <<EOF
template <class T> int foo()
{ throw 0; }
EOF
g++ -c -Wall test.cpp
test.cpp: In function `int foo()':
test.cpp:2: warning: no return statement in function returning non-void

This code compiles fine with gcc-3.3.1, so it's a regression.
