It doesn't turn up anything for me, either, because it is not an
executable, but a library. More to the point, you can find out if m4 is
using libsigsegv by inspecting your config.log output. For example, when
I built a recent development copy of m4, my config.log contains:
configure:7054: checking for libsigsegv
configure:7082: result: yes
configure:7088: checking how to link with libsigsegv
configure:7090: result: -lsigsegv
and further searching turns up /usr/include/sigsegv.h which includes:
#define LIBSIGSEGV_VERSION 0x0204 /* version number: (major<<8) + minor */
so my machine has libsigsegv 2.4 installed (no known bugs when used on
cygwin, but according to the NEWS file, this version is buggy on at least
Mac, BSD, and Linux; 2.6 is the most recent release, but even that still
has bugs on fringe platforms like Irix that are only fixed in CVS libsigsegv).

Are you comfortable using gdb (assuming you have that installed)? Are you
able to figure out how to run the failing test under gdb such that you can
give a stack trace at the point where the SIGBUS occurred, or would you
like a step-by-step walkthrough?
Don't work too hard, make some time for fun as well!
