gawk segfaults on opening non-existent file

[Rafael Garcia-Suarez]

Apologies if this was reported before, but I didn't find any archives.

It appears that gawk 3.1.5 segfaults if it tries to open a file that
does not exist. See the bug report at :
http://qa.mandriva.com/show_bug.cgi?id=20050
(but this is reproducible very simply).

I have written a patch to fix this : basically, avoid freeing a
pointer that will continue to be used afterwards.
Please find the patch in the CVS at :
