Comment(by RichardG):

 I've attached a somewhat simplified test case (it's HUnit with a bunch of
 stuff ripped out).  The {{{tests/SimpleTest.hs}}} file has 3 tests in it
 which compare the expected and actual results of a failed assert.  These
 are:

 {{{
 expectProblem Failure 0 "test" (TestCase $ assertFailure "test"),
 expectProblem Failure 0 "test" (test $ assertFailure "test"),
 expectProblem Failure 0 "test" ((TestCase . (>>= assert)) $ (assertFailure
 "test"))
 }}}

 The first test gives the expected result.  The second and third tests
 display the same erroneous behavior that is described in the original
 report (i.e., it behaves incorrectly only when compiled with GHC 6.12.1
 and Cabal).

 (The third test in the list is the second test where {{{test}}} has been
 replaced with, what I assume are, the appropriate functions.)
