[Fwd: gawk bug]

[Eiso AB]

hi again(?),

not sure if this got through yesterday, and I didn't include output.

the script produces
H99 N|
instead of the expected
H99 N

so in the second gsub not all |'s
are removed.

goodluck, Eiso

 hi Arnold,

this produces a bug in gawk 3.1.4


put this in an awk script (bug.awk)
{
          ( FILENAME ~ /[.]save$/ )
          h=$2
          gsub("[|]"," ",h)
          x=$1
          gsub("[|]"," ",x)
          print x
}

then run as

echo "|H99|N| |H99|HN|" > t.save ; gawk -f bug.awk t.save



removal of:
* ( FILENAME ~ /[.]save$/ )
* gsub("[|]"," ",h)
and change of the filename(!)
will make the error disappear.


very strange!
goodluck,

Eiso
