bug in gawk 3.1.5

[Alfred P. Steffens Jr.]

GAWK 3.1.5 produced a fatal error on the following script line:

if (match(field, /([0-9\.]+)([&@])([+-0-9\.\[\]!*qho])*/)) {

}

something about "bad range end".  This code works fine with GAWK 3.1.3.

The code is meant to parse symbols of the form

&
&+5
&+[!]
&+[*]
&+[q]
&+[h]
&+[o]
3.1&+[6!]
9&+[4.6*]
1.3&+[2.01q]
..........
or with a @ in place of the &.
@
@+5
@+[!]
@+[*]
@+[q]
@+[h]
@+[o]
address@hidden
address@hidden
address@hidden

  The idea is a "gain" number operating on a & or a @ and an "offset" 
that is either a number or a symbolic expression withing square brackets 
consisting of a sub-gain operating on a "!" or "*" or "q" or "h" or "o".



Operating system:  Slackware Linux rev 10.2 (kernel 2.4.31).
GCC:  It was a binary, so I don't know.  Probably 3.3.6.
