It started several weeks ago and has been happening intermittently ever since. So far it's only occurred during buildworld, not other compilations such as firefox (which still fails from porting issues). I couldn't find any recent posts on this error, is it worth a bug report? The information I could gather from the latest crash is at http://www.zefox.net/~fbsd/rpi2/crashes/crash_9_20_17/ Thanks for reading, and any guidance! bob prohaska
