Thanks for looking into this, Richard.  I should have mentioned that you'll

need to build with optimization turned on.



Expected behavior:

test.c built with -O -fno-builtin runs to successful completion



Actual behavior:

test.c built with -O -fno-builtin aborts (failed assertion)

test.c built with -O0 does not abort
