a bug in gawk-3.1.4

[Masahiko Furuichi]

I have a problem with gawk-3.1.4. gawk-3.1.3 seems OK.
Both gawk is compiled by gcc-3.3.4 + Solaris 8(SPARC). 

Here is the sample.

fs12{sbsoft}: cat sample
! 1
a b
! 2
c d
fs12{sbsoft}: ../gawk-3.1.3/gawk '/^[^!]/{printf("%s\n", $1)}' sample
a
c
fs12{sbsoft}: ../gawk-3.1.4/gawk '/^[^!]/{printf("%s\n", $1)}' sample
fs12{sbsoft}:

fs12{sbsoft}: ../gawk-3.1.3/gawk --version
