  * milestone:  => 6.6.1

Comment:

 This should be debuggable.  First try to find a program that isn't ghc and
 still crashes - start with `testsuite/tests/ghc-regress/codeGen`.  You'll
 need to run them the `threaded1` way: `make WAY=threaded1`.

 When you find a test that crashes, run it with `+RTS -Ds`.  Take a look
 with gdb and see if you can see where the `cap->in_haskell` field is not
 being set as it should be - there are only two places in the RTS where it
 gets set to true, both in [[GhcFile(rts/Schedule.c)]].
