[Bug c++/37719] New: incorrect type on warning of mismatched exception specification with templates

["yacwroy at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

========= test/test.cpp ==========
template <typename T>
class foo {
    void bar() throw(int);
};

template <>
void foo<int>::bar() throw(float) {}
========= COMMAND ==========
g++ -c -o test/test.o test/test.cpp -Wall
========= OUTPUT ==========
test/test.cpp:7: error: declaration of â??void foo<T>::bar() throw (int) [with
T = int]â?? throws different exceptions
test/test.cpp:3: error: from previous declaration â??void foo<T>::bar() throw
(int) [with T = int]â??
======== test.ii =========
# 1 "test/test.cpp"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "test/test.cpp"
template <typename T>
class foo {
    void bar() throw(int);
};

template <>
void foo<int>::bar() throw(float) {}
===========================
first line should be throw (float)


The error comes from in "gcc/cp/decl.c" in function
check_redeclaration_exception_specification() on line 1097, but I don't know
how to debug it yet.
