Provide adaptions of mallocForeignPtrArray and allocaArray that add stress tests and integrity checks. There are three modules: Guarded.Plain: exports the original allocation routines Guarded.Debug: exports allocation routines that add stress and checks Guarded: exports either Guarded.Plain or Guarded.Debug depending on the Cabal debug flag. It is intended that you always import the Guarded module in user code and install a package version with enabled debug flag to a custom package database for debugging. If you compile your user program you can choose production or debugging mode by choosing the default or the custom debugging package database, respectively. This package is inspired by the famous Amiga debug tool MungWall. The Linux counterpart is Electric Fence.
