Law <law at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED CC| |law at redhat dot com Resolution|--- |WORKSFORME --- Comment #3 from Jeffrey A. Law <law at redhat dot com> --- So I tried a variety of revisions from April 29, 2019, but was unable to reproduce this problem. I also tried a subset of those revisions under valgrind just in case there was an uninitialized read, memory corruption or the like. Other than the well known issues with sparsesets, nothing triggered. There are other ICEs from this gcc_unreachable that have been fixed, but from my research a variety of issues in allocation/reloading can be caught by this gcc_unreachable. I'm going to close this as WORKSFORME. Obviously if you can still reproduce, please reopen and we'll dig deeper. As always, thanks for your reports. Jeff
