Re: [bug-gawk] Yet another: pointer being freed was not allocated

[Aharon Robbins]

Hi.

Very nice test case. I will push a fix and add this to the test
suite in a few minutes.

Keep those cards and letters coming!  :-)

(The next time I add a new feature, I will point you at the branch
*before* I merge it into master. :-)

Thanks for exercising the code so well; I really appreciate it!

Arnold
