[bug-grep] Re: grep

[flavio]

Hello,

   thank you for your quick answer, just a few additional notes that I
hope will be useful for you.

The Bond test in backref.sh did not work in my brand new build (I had to
kill it), while it completed in a few milliseconds with the Slackware and
Cygwin builds. I tried to re-configure and re-make:

   ./configure --prefix=/usr --bindir=/bin --with-included-regex

and all the tests were good.

Now my problem is simple: should I keep this fresh build with the included
(but bugged, according to you) code, or should I stick to the system regex
code? I'm scared thinking that the Bond test didn't even exit, and this
could happen in future too, and having a return value of 1 instead of 2
scares me less at the moment :S

I'm also wondering why my Slackware grep did work on the Bond test given
that it should use the system library, but this surely is some difference
in library versions.

Thank you again,

   Flavio Poletti.
