There should be informative messages in the log, like "maximum coordination
exceeded...." that may be helpful. Do carbon atoms have a large number of
bonds in carboranes? Basically, the code in atom.c around line 385 triggers
a message when hydrogen has more than 1 bond, oxygen has more than 3 bonds,
or other elements have than 5 bonds. Does you molecule violate any of these?

As a test, you can try change line 385 in atom.c from "return(TRUE);"
to "return(FALSE);". I'm unsure whether or not defeating this test will
cause other problems or not....
