[platform-testers] new snapshot available: grep-3.1.48-7eea

Subject: [platform-testers] new snapshot available: grep-3.1.48-7eea

Here's another snapshot.
It should address the backref-alt failures via a change in gnulib's
m4/regex.m4: that will cause the use of package-supplied regex code,
since it detects the assertion failure in the glibc-provided function.

That change or the patch mentioned below may help with the
"stack-overflow" test failure Assaf reported on Ubuntu 14.04/aarch64.
The AIX 7.2 stack-overflow failure is different. There, gnulib's
c-stack module (for detecting stack overflow) may not work, since
I saw this in Assaf's log:

  ./stack-overflow: line 12: 19661370 Illegal instruction (core dumped)...

This should reproduce it:

  i=200; printf %0${i}0000d 0|tr 0 '(' > in; LC_ALL=C src/grep -Ef in; echo $?

Thanks for all the quick work already.
