The preprocessed source file is larger than 1Mb even compressed (by xz -9e), so run the following to get it.

$ fetch -qo- https://reviews.freebsd.org/paste/raw/404/ | b64decode -o /dev/stdout | xz -dc >System-095a42.cpp
Comment 2 Dimitry Andric freebsd_committer 2020-06-30 20:27:53 UTC
I have been able to reproduce this with the most recent upstream llvm-project checkout, and am now reducing the test case for submission into their bugzilla.
Comment 3 Dimitry Andric freebsd_committer 2020-07-02 13:51:00 UTC
Reduced and reported upstream: https://bugs.llvm.org/show_bug.cgi?id=46557
Comment 4 Jan Beich freebsd_committer 2020-07-03 08:31:12 UTC
I can't reproduce on 11.4 and 12.1: upstreamed sample and the port build fine. Tested base Clang 8.0.1, base Clang 10.0.0 and ports Clang 10.0.1 rc2.
Note, on -CURRENT even ports Clang 10.0.1 rc2 does NOT crash but it's built with -DNDEBUG due to bug 233506.
