Re: gawk: Internal Error

[Aharon Robbins]

Greetings.  Thanks for the bug report.

The version of gawk you're using is very much out of date.  The current
version is 3.1.0, which has many new features and many bug fixes.  When I
run your program with your data on the current gawk, it exits quietly,
without failing.

I suggest you upgrade; the latest version is available from a GNU mirror
near you.

Thanks,

Arnold Robbins
