https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D259799 --- Comment #41 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to Mark Millard from comment #36) I finally got a no-strip (but no debug information) environment set up where I can look at the main [so: 14] based build failure via a backtrace. This is still an optimiazed build so there could be oddities in the backtrace but it should be useful:. It looks like: rustc_errors::Handler::delay_good_path_bug () from /usr/local/lib/librustc_driver-a196dfc434d07325.so initiated the backtrace that is later problematical. gdb reports: Core was generated by `/usr/local/bin/rustc --crate-name tempfile --edition=3D2018 /wrkdirs/usr/ports/dev'.
