In particular, this leads to false positives on MALLOC_PRODUCTION when matching a pattern with multiple dots some of which may be escaped. http://svnweb.freebsd.org/changeset/base/225435 (merged into /head) >How-To-Repeat: $ make all install WITHOUT_NLS= -C/usr/src/usr.bin/grep $ echo 'f.oo' | env -i MALLOC_CONF=junk:true bsdgrep -o 'f.o\.' Exit 1 $ echo 'f.oo' | env -i MALLOC_CONF=junk:false bsdgrep -o 'f.o\.' f.oo $ echo 'f.oo' | env -i MALLOC_CONF=junk:true gnugrep -o 'f.o\.'
