(In reply to Steve Wills from comment #28)
Yes, as mentioned in bug 258954, OpenJDK 11 through 13 use undefined behavi=
or,
and this will trigger segfaults with llvm >=3D 13.

This has been fixed in OpenJDK >=3D 14, but the diffs are very difficult to
backport to older OpenJDK versions (and upstream did not do it either, as f=
ar
as I know). Therefore those older versions must be compiled with devel/llvm=
12.
