The question isn't which version of autoconf, but which version of m4.
What does 'gm4 --version' output?  Did you build /opt/local/bin/gm4
yourself, or was it pre-installed?

The debug output given by 'make -D' doesn't add any information: it is not
make that is crashing, but m4.  What I was asking for is a call trace from
m4 at the point where it crashed.  Assuming that /opt/local/bin/gm4 is
indeed m4 1.4.12, and that you built it (or can reproduce the build,
starting from the release tarball), then it helps to make sure that m4 is
built with debugging symbols (./configure CFLAGS=-g).  Also, m4 1.4.12
normally catches SIGBUS to display a nice error message with the bug
reporting address; but now that we know a SIGBUS is happening, it might be
easier to actually dump core at that point, so gdb can display the
stacktrace from the core dump.  To do that, comment out the four sigaction
calls in lines 401-404 of src/m4.c prior to compilation.
