There are many places in other GNU apps, including gnulib, where
it's assumed that one can declare a 4 kB-or-so array on the stack without
any problem.  So I'm surprised to see the need for this change to GNU grep.
Surely we don't need to go through GNU apps and rejigger things for
configurations with 4 kB stacks?  By today's standards, such stacks are
ridiculously small.
