Bug #: 11850
Summary: empty function parameter pack expansions before the
end of the parameter list don't work
Product: clang
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++0x
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
This crashes clang:
template<typename ...T> struct S {
int f(T...a, int b) { return b; }
};
S<> s;
int k = s.f(0);
... like so:
lib/Sema/SemaTemplateInstantiateDecl.cpp:2549: void
clang::Sema::InstantiateFunctionDefinition(clang::SourceLocation,
clang::FunctionDecl *, bool, bool): Assertion `FParamIdx <
Function->getNumParams()' failed.
This is rejected:
template<typename ...T> void f(T...a, int b) {}
template void f<>(int b);
... like so:
<stdin>:2:15: error: explicit instantiation of 'f' does not refer to a function
template, member function, member class, or static data member
template void f<>(int b);
^
I believe both of these cases should work.
