I'm not actually seeing any memory leak. The memory lost during a single iteration remains zero at least through iteration 29. (The total memory lost stays constant...my interpretation is the value is the memory taken by the bridge object)

The IDL docs on OBJ_DESTROY suggest using the cleanup method is better in the instance of recursive object definitions (and I've no clue if IDL_IDLBridge generates objects within itself) so I thought to try "o->Cleanup" (despite the docs saying that "o->cleanup" is the same as "OBJ_DESTROY, o").

Also, in this example a new object is created and destroyed each iteration. If I rewrote this to mirror my own implementation, it would create the bridge once and then each iteration it would use setvar, execute, then getvar (or in this case just use execute each iteration). This also has the benefit of avoiding the overhead of creating and destroying the objects, but I'm unsure as to what impact it has on any memory leak.

Regardless, here's my version structure if you're interested:
{ x86_64 linux unix linux 8.2.3 May 2 2013 64 64}
