Summary0000112: Compiler crashes with code 10 when table defines an object that exists in another context
DescriptionInform will sometimes fail to catch that an object defined in a table has also been defined in another context (e.g. a room). When this happens, the compiler halts with code 10 during the drawing inferences phase.

It is unclear precisely what causes Inform to miss the duplication of the object name. For the source code given, the following are necessary conditions:

1) The room must be defined as part of a complex assertion ("Up from Entrance Chamber is Shaft") rather than a simple one (e.g., "Shaft is a room").
2) The object defined in the table must have at least one property defined along with it.

Change either of these and Inform will correctly diagnose the problem, avoiding Type 10 failure.
Minimal Source Text To Reproduce
Entrance Chamber is a room.

Up from Entrance Chamber is the Shaft. 

A badass is a kind of man. Some badasses are defined by the Table of Badassery. A badass has a number 
called the BA quotient.

Table of Badassery
badass	BA quotient
Shaft	10
Additional InformationThis is possibly the same as issue 0000044, but it seems to arise from a different situation.

A crash while attempting to produce a helpful problem messages. Some days, it just doesn't pay to be helpful. Fixed.
