Details:

First, error is returned with collating element in grep-2.6.3.

$ /bin/echo achb | LC_ALL=es_US.iso88591 src/grep 'a[[.ch.]]b'
src/grep: Invalid collation character
$

This message is generated at `re_compile_pattern',
but we don't use GNU regex for for this searching.
Therefore next I comment out dfasearch.c:130-162, rebuild and re-run.

$ /bin/echo achb | LC_ALL=en_US.iso88591 src/grep 'a[[.ch.]]*b'
$
(expected `achb')

$ /bin/echo achb | LC_ALL=en_US.UTF-8 src/grep 'a[[.ch.]]b'
Segmentation fault (core dumped)
(expected compile-error)
$



Configure options: ./configure --with-included-regex

$ LC_ALL=C src/grep --version
GNU grep 2.6.3
