            Bug ID: 65389
           Summary: long compile time on incorrect code with lambdas
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vanyacpp at gmail dot com

The following program takes ages to compile:

template <typename F, typename FF>
void demangle_type_rec(F out, FF prepend_suffix)
{
//    int class_type = // uncomment to get infinite stream of error messages
    demangle_type([&] {});
}

template <typename Out>
void demangle_type(Out out)
{
    demangle_type_rec(out, [&] {});
}

void print_seqid()
{
    demangle_type([&] {});
}

Probably it is possible to limit the compilation time on this incorrect case?
