Either the package or from source.

Do I need to report this upstream or someone else has already encountered this problem?

Environment:

macOS 10.14.6 18G9323 x86_64
Xcode 10.3 10G8
macports latest from git

This seems to be where it's crashing: https://gitlab.com/samba-team/samba/-/blob/master/third_party/heimdal/lib/gssapi/mech/gss_oid_equal.c
