Issue created May 04, 2006 by Simon Peyton Jones@simonpjDeveloper

Breakpoint mechanism crashes when there's a type error

Test tcfail032 is failing thus;

- tcfail032.hs:14:7:
-     Inferred type is less polymorphic than expected
-       Quantified type variable `a' is mentioned in the environment:
- 	x :: a -> Int (bound at tcfail032.hs:14:2)
-     In the expression: x
-     In the expression: (x :: (Eq a) => a -> Int)
-     In the definition of `f': f x = (x :: (Eq a) => a -> Int)
--- 1,6 ----
+ ghc-6.5: panic! (the 'impossible' happened)
+   (GHC version 6.5 for i386-unknown-linux):
+ 	find_thing Identifier `breakpointJump{v 011}'

Something to do with the new breakpoint mechanism.
