On /stable/9 and less jemalloc options syntax is different:
MALLOC_CONF=junk:true -> MALLOC_OPTIONS=J
MALLOC_CONF=junk:false -> MALLOC_OPTIONS=j
cf. malloc(3) manpage e.g.,
Other flags control boolean parameters, where uppercase indicates
that a behavior is set, or on, and lowercase means that a behavior
is not set, or off.
>Description:
(originally reported to gabor@ on 04 Dec 2011)
After r225435 bsdgrep built WITHOUT_NLS became sensitive to whether
allocated memory but not initalized memory is set to NULL or junk. In
particular, this leads to false positives on MALLOC_PRODUCTION when
matching a pattern with multiple dots some of which may be escaped.

>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\.'
Exit 1
$ echo 'f.oo' | env -i MALLOC_CONF=junk:false gnugrep -o 'f.o\.'
Exit 1
