Plug-in fclang aborted: internal error.
Please report as 'crash' at http://bts.frama-c.com/.
Your Frama-C version is Neon-20140301+dev-STANCE.The problem remains if some member variable (e.g. "int x;") is added to the body of class "Matherr" in line 2 or/and the body of class "Underflow" in line 3.
The problem disappears if either: (1) the definition of "Underflow" in line 3 is deleted, (2) the definition of "foo" in line 5-10 is deleted, (3) "Matherr" is changed to "Underflow" in the catch statement in line 8, or (4) "public" is changed to "private" in line 3.
