Re: gawk: "please file a bug report"

[Denis Shirokov]

Hi!

I've encountered this error many times but could never find a
reproduce script. I can only say that it was never related to gensub,
gsub or sub. and it was definitely not related to the strong regexp
datatype.

sometimes the elements of an array determinated by typeof() as unknown
and thats all what i know about it.

Kind Regrds
