[GemStone-Smalltalk] Variables and block closure

[James Foster via GemStone-Smalltalk]

There are some bugs in the way blocks handle variables in GemStone/S 64-bit 3.2.x (and possibly earlier; you don’t mention your version) that will be fixed in 3.3 (but probably not before; this is described internally with bug #45059).
