--- Comment #2 from Kyle Evans <bsdports@kyle-evans.net> ---
(In reply to Jan Beich from comment #1)

D'oh. This is a trivially broken case; easily exceeds the maximum number of
line matches (MAX_LINE_MATCHES=3D32), then it infinitely loops because it s=
till
matches past that but it's not able to be inserted into 'matches,' causing =
my
failure mechanisms to fail because $bad.

I'll fix this in my -w empty broken review (https://reviews.freebsd.org/D10=
433)
version, because it's *not* straightforward to fix this on -HEAD since
procline() conflates matching a line with printing context. In the current
state of that patch, this will basically record 'st' and set lastmatches=3D=
0,
force a break at util.c:443, then at util.c:284 I'll throw in a loop that d=
oes
a procline() and printline() as long as we max out on matches.

Thanks for the report! =3D)
