Reproduced. We have __dynamic_cast without DECL_CONTEXT and so ICE in
9050 if (!DECL_CONTEXT (t))
9051 {
9052 /* There are a few cases of decls with no context. We'll write
9053 these by value, but first assert they are cases we expect. */
9054 gcc_checking_assert (ref == WK_normal);
9055 switch (TREE_CODE (t))
9056 {
9057 default: gcc_unreachable ();
PR 106304 has a much simpler single-file reproducer that ICEs at the same line. I had a issue I believed to be related but in attempting to create a reproducer got several different ICEs so I have submitted a separate ticket - see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107191 Same issue as the recently fixed PR106304 *** This bug has been marked as a duplicate of bug 106304 *** |
