Segmentation Fault on config verification

Seeing this on 3.3.1, and 3.4.1.  Tried to reproduce with 4, but can't 
build from the current git repository.

Migrating from obj_file to obj_dir style nagios.cfg, and on validation 
of my Master configuration I get a Segmentation fault, that looks to be 
coming right after Nagios closes nagios.cfg.

The same format of configuration, generated from the same script works 
fine for poller nodes.  The main differences in the poller node 
configuration is size, no escalations, and no dependencies.

The end of the truss output:
mmap(0x0,783,PROT_READ,MAP_PRIVATE,5,0x0)        = 34365812736 (0x8005cb000)

close(5)                                         = 0 (0x0)

process exit, rval = 0

I'm digging into the source, but if anyone has any ideas, I'm ears.
