test_compiler and test_transformer are failing due to the fact that the compiler package still needs some TLC to catch up with the Grammar changes.

test_logging, test_tcl and test_structmembers all fail when run with -R 4:3:. However, these failures don't appear to be due to this change. More importantly, no leaks are reported in the new tests that are part of this update (test_listcomps, test_setcomps).

Committed as rev 54835.
