There is a - .toupper \\$* - manual problem yet.
Samba 3.0 was fixed just before 4.7, but here is an other:
maildrop-2.2.0p1: maildrop(1), maildropfilter(7), maildir(5)
According to grep there is not any more so string (with my installed packages).
The problem is the same as with Samba:
---
man maildrop
man: Formatting manual page...
/usr/local/man/man1/maildrop.1:60: fatal error: input stack limit exceeded
(probable infinite loop)
MAILDROP(1) Double Precision, Inc. MAILDROP(1)
---
.ie n \{\
.\" if n (TTY output), use uppercase
.toupper \\$* # Line 60
.\}
OpenBSD 4.7-current (GENERIC) #572: Tue Mar 30 19:14:44 MDT 2010
dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC
mandoc 1.9.19
groff 1.15
What is the solution?
Updating maildrop, courier, something else ports?
Removing the ".toupper \\$*" lines?
In base system something?
