Bug ID: 63367
Summary: internal compiler error: tree check: expected
function_decl, have template_decl in warn_hidden, at
cp/class.c:2824
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: cas43 at cs dot stanford.edu
When trying to compile this:
class A {virtual void f();};
class B : public A {template<class T> void f();};
Run like this:
g++ -Woverloaded-virtual -c prog.cpp
I get this output:
prog.cpp:2:7: internal compiler error: tree check: expected function_decl, have
template_decl in warn_hidden, at cp/class.c:2824
class B : public A {template<class T> void f();};
