Actually, I think that even with your gnulib patch, we will still see this
failure, since m4 installs its own SIGBUS handler after calling
c_stack_action, thus undoing the SIGBUS handler that your patch added in
c-stack.c.  Hmm, maybe swapping the order will help, where I install the
SIGBUS handler first, and then c_stack_action can optionally install an
alternate handler on platforms where it is needed for stack overflow?
