(I assume system-clang/llvm was in use instead of devel/llvm* 's. This wording
presumes that the 11.4 and 12.1-STABLE system clang 10 based rxdock builds were
separate. If not, do the contrasting case implicit below.)
If you copy the rxdock installed materials from 11.4 to 12.1-STABLE, do you see
the
problem on 12.1-STABLE? This is different than building rxdock materials on
12.1-STABLE with the 12.1-STABLE's llvm10/clang10 toochain. This is sort of
like
upgrading FreeBSD after the rxdock software was installed, without rebuilding
the
rxdock software. (That is another way of doing the experiment.)
The alternatives would seem to be:
A) Still works on 12.1-STABLE, so that 12.1-STABLE's toolchain is involved for
the behavioral change in the re-built rxdock.
vs.
B) Fails on 12.1-STABLE, so just other differences in the FreeBSD versions make
the difference, not the toolchain used to do the build (rxdock held
invariant).
So it is just a partial problem-isolation test but it might help limit what
else to explore.
Of course, the suggestion presumes that FreeBSD's backwards compatibility
support has been built and installed in the 12.1-STABLE system, so that
the 12.1-STABLE is supposed to execute 11.x material just fine.
