Re: [bug-gawk] problem with 'match'

[Antonio Giovanni Colombo]

Hi everybody,

testing under Linux OpenSuSE 11.4 (32 bits),

both gawk V3.1.6 and V3.1.82 give the

same expected result (209).

Before going further, I would suggest

to try the last version of gawk:

git clone git://git.savannah.gnu.org/gawk.git

to get the source, and then

./configure

make

make check

make install

All the best, Antonio

Dear awk management team,

I have create on top of gawk a tool to extract tags and links from HTML files.
With gawk V3.1.1 from RHEL V3.0 WS (32b), the tool is perfect.
With gawk V3.1.8 from Fedora Core 14 (64b), the tools exhibits problems.
Here is a simple instance to create the problem:

awk 3.1.1:
./awk '{printf "%d\n", match($0, "<[ ]*[aA][ ]+[hH][rR][eE][fF]")}' test.txt
gives 209, the expected result

awk 3.1.8:
/bin/awk '{printf "%d\n", match($0, "<[ ]*[aA][ ]+[hH][rR][eE][fF]")}' test.txt
gives 1, an erroneous value

Please note that line selection with the same regular _expression_ works properly with both awk versions.

I hope it helps. Best regards,

Guy Léonis
