Description ksmakoto 2014-03-16 14:00:00 UTC
m4 segv, when processes "ifelse(a,b,c,d,d)".

How-To-Repeat: $ echo 'ifelse(a,b,c,d,d)' | m4
Segmentation fault: 11 (core dumped)

This patch will ensure that m4 does not try to evaluate a set of 
arguments that does not adhere to the instructions in the man page:
