Looks like a compiler specific problem to me: When I try, on a Solaris 10
system, the Sun C 5.8 compiler, all tests pass (after applying Eric's
test-closein patch).

With the configure settings that were reported, vasnprintf is implemented
through lib/vasnprintf.c. Can you try to build m4 (freshly unpacked from
the .tar.gz file) with CC="cc -O" or CC="cc" instead of
CC="cc -fast -xautopar"?

regex.c and vasnprintf.c contain big functions; this is a second (weak)
indication of a compiler problem.
