This is a follow-up containing the test-suite log. I sent the email inside the box this time.

To GNU Grep Bug team,

I was building grep 3.1 for Linux From Scratch 8.3 Chapter 5.25 when the test suite(make check) returned one "XPASS." I was told by the suite to make a bug report and here it is.

I am running Windows 7 64-bit with VirtualBox 52.22
I've allocated the box 2G of RAM and 2 2GHz cores.
Inside the box, it is Ubuntu 18.04 64-bit.

Since I am running the whole thing inside a virtual box, it is hard for me to email the actual log contents(I am writing from outside). Let me know if you need the test-suite.log file.

Best Regards,

William
