Unfortunately this still appears to be some sort of bug. The solution given
with the -mstrict-align worked for the test case, but in the specific case
here, still fails. Attached is the output of the link command given. The
compiler invocation for all of the associated files that make the libraries,
and object files all contain the -mstrict-align.
