Bug ID: 63385
Summary: internal compiler error: in pop_binding, at
cp/name-lookup.c for implicitly captured variable
called closure
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> void f(F closure) { auto g = [&]() { return closure; }; }
Compile with 'g++ -std=c++11'. Output with gcc 4.8.3:
internal compiler error: in pop_binding, at cp/name-lookup.c:382
template <typename F> void f(F closure) { auto g = [=]() { return closure; };
}
