-------------------------------------+--------------------------------------
The type `FinalizerEnvPtr` and, more importantly,
 the function `newForeignPtrEnv` specified in Section 5.5 of the FFI
 addendum
 are missing from the GHC version of the `Foreign` libraries.
 There is not even a comment about this in `base/GHC/ForeignPtr.hs`.
 (I checked the source of the last nightly snapshot --- not there either.)

 I have reason to believe that my current attempts to use a `"wrapper"`
 foreign import
 to achieve the effect of `newForeignPtrEnv` are the reason behind
 segmentation faults
 I haven't (yet) been able to track down to anything else.

 Since these segfaults are a blocker for me, and since this is a point of
 non-conformance
 to a 'Standard', I proposed priority 'high'.

 (This is obviously operating system and architecture independent,
 but neither 'Unknown' nor 'multiple' in the menus below seem appropriate.)
