Bug ID: 70417
Summary: New g++6 rejects previously valid code
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jengelh at inai dot de
CC: rguenther at suse dot de
Target Milestone: ---
---8<---
template<class T> struct ref {
template<class U> ref<U> dy() const { return ref<U>(); }
};
template<class X, class Y> ref<X> dy(ref<Y> y) {
return y.dy<X>();
}

gcc version 6.0.0 20160324 (experimental) [trunk revision 234449] (SUSE Linux)
produces:
t.cpp: In function ‘ref<X> dy(ref<Y>)’:
t.cpp:5:15: error: expected primary-expression before ‘>’ token
return y.dy<X>();
^
t.cpp:5:17: error: expected primary-expression before ‘)’ token
return y.dy<X>();
^
Prior g++ versions, including
* gcc version 4.8.5 (SUSE Linux)
* gcc version 5.3.1 20160301 [gcc-5-branch revision 233849] (SUSE Linux)
* and some un-rememberable g++6 "from last month or so"
all accepted the code. Is there something new in the C++ standards, or is this
a g++ regression?
