I see these failures too, they appear to have started with SVN version 114783.
I don't think that patch is buggy, it just preterbed the allocation setup
enough to make something that was accidentally aligned to be accidentaly
unaligned.

If I am reading the assembly correctly the unaligned access is happening in
build_string (tree.c) with the inlining of memcpy.  Why GCC would be assuming
something more than char/byte alignment, I don't know.
