gawk v 3.1.1 match function bug

[Peter Leggett]

Hi,

I think there is a bug with the match function in gawk 3.1.1 (as released with
RedHat 9) and case matching.

Here is a simple example of the bug.

address@hidden src]$ uname -a
Linux wiggen 2.4.20-18.9 #1 Thu May 29 06:54:41 EDT 2003 i686 athlon i386 
GNU/Linux
address@hidden src]$ gawk --version
GNU Awk 3.1.1
address@hidden src]$ more testdata
ABC
abc
address@hidden src]$ gawk '{ print match($0,/[A-Z]/) }' < testdata
1
2
address@hidden src]$


And to show it works on an earlier version

address@hidden 110 % uname -a
SunOS herman 5.8 Generic_108528-19 sun4u sparc SUNW,Sun-Blade-1000
address@hidden 111 % gawk --version
Gnu Awk (gawk) 3.0, patchlevel 0
address@hidden 112 % more testdata
ABC
abc
address@hidden 113 % gawk '{ print match($0,/[A-Z]/) }' < testdata
1
0
address@hidden 114 %

Please accept my apologies in advance if this bug has already been reported
or is not a bug but a product of a mis-understanding on my part.

Kind regards

Peter
