When building from poudriere, xmlto fails to build the git documentation. This is caused by an underlying segmentation fault in xsltproc.

Rebuilding libxslt-1.1.28_7 doesn't seem to help fix this. 

xmlto -m ../../Documentation/manpage-normal.xsl man git-subtree.xml
/usr/local/bin/xmlto: line 585: 35665 Segmentation fault      (core dumped) "/usr/local/bin/xsltproc" --nonet --xinclude --param passivetex.extensions '1' -o "/tmp/xmlto.Pa861F/git-subtree.proc" "/tmp/xmlto-xsl.pBst4O" "/usr/ports/devel/git/work/git-2.5.3/contrib/subtree/git-subtree.xml"

/usr/local/bin/xsltproc --nonet --xinclude --param passivetex.extensions 1 -o /tmp/xmlto.ePqpYB/git-subtree.proc /tmp/xmlto-xsl.5ykwCy /usr/ports/devel/git/work/git-2.5.3/contrib/subtree/git-subtree.xml

xsl files are attached.

After spending a few months on and off analyzing this core dump and the program, this comes about because of the recommended settings for DTrace.

https://wiki.freebsd.org/DTrace/userland

CFLAGS+=-fno-omit-frame-pointer

This library uses the frame pointer for its own work. Omitting this flag for the build of this specific port gets rid of the bug.
