[Haskell-cafe] not for me, guv!

[Evan Laforge]

So I wrote a big email about this mysterious message I was getting,
but then after some research and poking and debugging tracked it down
to a dangling pointer in C that was causing a callback to point to an
invalid address, which somehow worked anyway 99% of the time.

That all said, I'm not totally convinced that "freeHaskellFunctionPtr:
not for me, guv! 0x23143f0" is the clearest error message ever.  Now,
if it were in a more contemporary American idiom such as "wtf this ptr
ain't from MY house lol!!!" I probably would have found the bug in
half the time.

Anyway, I fixed my bug and I'm happy about that, but I didn't want to
waste a chance to send an email with this title...
