possible gsub() bug

[Teemu Ikonen]

Hi,

gsub seems to do incorrect substitution in some cases.

Example script (example.awk)
============================

BEGIN {
  IGNORECASE=0;
}

{
     gsub("[A-Z][A-Z]*:","");
     print $0;
}


Exaple run:
===========

elaboration /tmp $ gawk -f example.awk
ID:address@hidden:1234       <--- input from console
address@hidden
ID:address@hidden:1234    <--- input from console
address@hidden

I would expect to see:
======================

elaboration /tmp $ gawk -f example.awk
ID:address@hidden:1234       <--- input from console
address@hidden:1234
ID:address@hidden:1234    <--- input from console
address@hidden:1234
