Bug #: 55408
Summary: ICE for member template definition with non-type
variadic parameter
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: lucdanton@free.fr
Created attachment 28740
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28740
Reproducible testcase
$ g++-snapshot --version
g++-snapshot (Debian 20120915-1) 4.8.0 20120915 (experimental) [trunk revision
191353]
When attempting to compile this program:
struct foo {
template<int*>
void bar();
};
template<int*...>
void foo::bar() {}
int main()
{
extern int i;
foo {}.bar<&i>();
}
GCC complains:
main.cpp: In function 'int main()':
main.cpp:12:21: internal compiler error: Segmentation fault
foo {}.bar<&i>();
^
Some casual investigating suggests that this happens every time the definition
for a member template is exactly the same as its declaration save for the fact
that a non-type parameter is made variadic. Otherwise, e.g. if the parameter in
question is a type or template parameter in the declaration or if the template
is declared taking int and defined taking long... then GCC correctly reports
that the definition doesn't have a match.

We reject this:
struct foo {
template<int*>
void bar();
};
template<int*, int>
void foo::bar() {}
But incorrectly accepts:
struct foo {
template<int*>
void bar();
};
template<int*...>
void foo::bar() {}
