Summary: [4.8 regression] ICE in value_dependent_expression_p,
at cp/pt.c:19551
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: manisan...@gmail.com
gcc version 4.8.0 20130220 (Red Hat 4.8.0-0.14) (GCC)
g++ -c ice.cc
ice.cc: In function ‘void foo()’:
ice.cc:19:25: internal compiler error: in value_dependent_expression_p, at
cp/pt.c:19551

========== ice.cc ==========
struct A { };
A& operator<<(A&, const char*);
struct B {
int size();
};
struct C { };
template <class S, class T>
S bar(const S& s, const T& t) {
return s;

a << bar(b.size(), C());
}
===========================
gcc version 4.7.2 20121109 (Red Hat 4.7.2-9) (GCC), gives get the expected
result
g++ -c ice.cc
ice.cc: In function ‘void foo()’:
ice.cc:19:25: error: no match for ‘operator<<’ in ‘a << bar(b.B::size(), C())’
ice.cc:19:25: note: candidate is:
ice.cc:2:4: note: A& operator<<(A&, const char*) <near match>
ice.cc:2:4: note: no known conversion for argument 2 from ‘int’ to ‘const
char*’
