Hello,

Sorry if this is not right list to post bug report but I can't find
where to post it.

On Alpine linux (musl libc) we discovered 'Segmentation fault' when
running 'man nft' (nftables man page).

We have mandoc (named mdocml=1.14.5-r0 in our distribution) and it works
fine, except this for 'nft' man page.

This is excerpt from 'ltrace man nft':
putwchar(9472, 9472, 0x7fe813c0bbab, 0)
strcmp(nil, "\\^" <no return ...>
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++

I looked in source and found problem in tbl_term.c file.
I made crude hack by removing few lines in tbl_term.c and build mandoc
again and with these changes it works without (visible to me) problem
for man pages I tried and for nft man page.

I'm attaching patch I made, but I think it is not proper fix and hope
that some of you experienced in this will make proper fix.
File I'm attaching is just hint.
