All I get are core dumps right on startup (amd64, default/empty
`vm.malloc_conf'); it does not matter if I build with `-fcommon' or
apply fixes from FreeBSD, same crash.
Installing with DEBUG='-g3 -O0 -fcommon':
$ hnb
Segmentation fault (core dumped)
$ egdb --quiet hnb hnb.core
Reading symbols from hnb...done.

Core was generated by `hnb'.
Program terminated with signal SIGSEGV, Segmentation fault.

I've used `cd $(make show=WRKSRC) && cc -E ./tree.c' to see what it does
at line 52:
Node *node_backrecurse (Node *node)
{
if ((((node))?((node)->up):0)) {
No idea why or how, but that seems plain broken regardless of
`-fno-common'.
OK to remove?
