* 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)]].
