Bug ID: 63423
Summary: internal compiler error: in
cp_parser_abort_tentative_parse, at cp/parser.c
Product: gcc
Version: 4.8.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: kretz at kde dot org
Testcase:
template <typename F, typename A,
typename = decltype(static_cast<void (&)(A &)>(F::operator())(A()))>
void test();
Compile it with '-std=c++11'. Tested to fail with GCC 4.8.[0123]. GCC 4.9.x
does not fail.
Output from GCC 4.8.3:
ice.cpp:2:76: internal compiler error: in cp_parser_abort_tentative_parse, at
cp/parser.c:23778
typename = decltype(static_cast<void (&)(A &)>(F::operator())(A()))>
