glibc's regular expression engine crashes with segmentation fault whenever 
trying to compile a regular expression with non-ASCII range expressions if
LC_CTYPE is a UTF-8 locale but LC_COLLATE is set to C or POSIX. This
is a common setup among users who want traditional codepoint-order
sorting but need UTF-8 encoding.

$ LANG=en_US.UTF-8 LC_COLLATE=C grep '[Á-ä]'
Segmentation fault

This is also reproducible with a simple C program.
