Summary: pci->fcn = 0 in malAtomProperty: segfault
Initial Comment:
Feb2010 CVS.
OpenBSD 4.6
gcc 3.3.5 (propolice)
Trying to start database, the mserver5 dumps core.
At line 92 of mal_atom.c, code tries to dereference null pointer:
case 'n':
if( idcmp("null",name)==0 && pci->argc==1){
-----> ptr atmnull = ((ptr (*)(void)) pci->fcn) ();

Message:
Indeed, the server should come to a graceful stop. More defensive code is
added.

Message:
Looks like a loader path issue.
But shouldn't the server fail earlier and harder?
Can the server ever function normally if the mdb (or blob, or calc, or
...)
library is not found?
