David Malcolm <dmalcolm at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |WAITING --- Comment #6 from David Malcolm <dmalcolm at gcc dot gnu.org> --- I attempted to reproduce using the issues described in comment #0, comment #3 and comment #4 (using r266145, fwiw). The only one I was able to reproduce was the final one in comment #4, for which I saw a different backtrace to the ones in comment #0 and comment #3. The patch in comment #5 should address the two backtraces; see: https://gcc.gnu.org/ml/gcc-patches/2018-11/msg01380.html for more notes on it. Does it fix things for you, or are you still seeing assertion failures inside the dump API?
