$ perl -e "m#:#'^J'"
Assertion failed: file "toke.c", line 202 at -e line 2.

the ^J is the embedded literal newline

# happens in a file also
$ echo  "m#:#'^J'" > toke.bug ; cat toke.bug ; perl toke.bug
Assertion failed: file "toke.c", line 202 at toke.bug line 2.

obviously this assertion is not invariant. :-)
maybe it would be true if I never made typo's in my code :-)
