When TIBCO detects a circular reference in bytecode, and copies a value to disconnect it, it fails to call TclReleaseLiteral() to decr the literal refcount of the value being discarded.
Replacing Tcl_DecrRefCount() with TclReleaseLiteral() should be enough to fix. See branch bug-3607372.
Fixed for 8.6.1.
