* Fix elemIndices and split
Ignore-this: 69ae945462b5638c99cc1824ed329e90
They were using inlinePerformIO to lazily delay IO actions within the
scope of a withForeignPtr. Thus the ptr was still in use after the
ForeignPtr went out of scope. This lead to dangling pointers, incorrect
results and segfaults. Nasty. See ghc tickets #3486 and #3487.
Audited the rest of the code base for the same anit-pattern.
Thanks to nwn and people on the haskell-jp mailing list for reporting
the bug with nice test cases and also to Ian, Bertram and Don for
diagnosing the source of the problem.
