Hi Ingo,
I have a very old OpenBSD/amd64 installation has been getting upgraded
since probably the very first amd64 release. The wonderful side effect of
this is I have an incredible amount of junk lying around. So, today after
upgrading to 5.8 I ran:
% makewhatis /usr/share/man
assertion "n->parent->type == ROFFT_BLOCK" failed: file
"/usr/src/usr.bin/mandoc/roff.c", line 1056, function "roff_node_append"
This looked awesome enough to prompt me looking. After a debug build I got
the stack trace (side note: it would be awesome if I could easily get the
debug versions of the release more easily than building from source).

Look what I got here, an awesome file from 2011! This one in particular:
-r--r--r-- 2 root bin 81212 Aug 17 2011
/usr/share/man/man7/mandoc.samples.7
Diff says the file is identical to that which was removed from the tree
over 4 years ago, but in case this stack trace is an interesting
reproduction case, you know where to find the input:
http://cvsweb.openbsd.org/cgi-bin/cvsweb/~checkout~/src/share/man/man7/Attic/mdoc.samples.7?rev=1.91
Thanks
Greg
