GC assertion failure in reactive program
In the same vein as bug #3279, this time I've triggered an assertion failure in the GC by adding Debug.Trace.trace expressions.
The exact same failure occurs in both 6.10.3 and 6.11, apparently completely deterministically.
A darcs patch to add the crash to reactive, and a program to trigger it, are both attached.
