Hmm, then one could just patch those 2 progs to ignore SIGFPE...

This shouldn't happen. According to:

https://www.x.org/releases/current/doc/libXt/intrinsics.html

```
Inheritance of Superclass Operations
[...]
Inheriting works by comparing the value of the field with a known,
special value and by copying in the superclass's value for that
field if a match occurs. This special value, called the inheritance
constant, is usually the Intrinsics internal value _XtInherit cast
to the appropriate type. _XtInherit is a procedure that issues an
error message if it is actually called.
```

_XtInherit() should never get called.

Does this happen on a real card attached to the VAX too? Because, this should've
been spotted a long time ago. Or, is X fundamentally broken on VAX?
