(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=2018 /wrkdirs/usr/ports/dev'.
Program terminated with signal SIGSEGV, Segmentation fault.
