--- Comment #31 from David Binderman <dcb314 at hotmail dot com> --- (In reply to Martin Liška from comment #30) > What's the project where you see the issue? Chatterino2, in fedora rawhide. Be warned, you will need my environment for gcc to see the problem. More thought suggests that in a usual crash, I get a preprocessed file, because I have -freport-bug switched on. In this case, source code file gcc/options-save.c explicitly calls routine internal_error, which doesn't produce a preprocessed file and so I cannot make progress. I am busy with other stuff right now, but by the weekend, I should be able to enhance routine internal_error to produce a preprocessed source code file and so we can make progress.
