test case

When catching an exception in a property accessor, valac gets stuck in an infinite loop with the following messages:

** (valac:4377): CRITICAL **: vala_symbol_get_scope: assertion `self != NULL' failed
** (valac:4377): CRITICAL **: vala_scope_lookup: assertion `self != NULL' failed
** (valac:4377): CRITICAL **: vala_code_node_get_parent_node: assertion `self != NULL' failed
** (valac:4377): CRITICAL **: vala_code_node_get_parent_node: assertion `self != NULL' failed
** (valac:4377): CRITICAL **: vala_symbol_get_parent_symbol: assertion `self != NULL' failed

This used to work--I haven't bisected it, but I believe the regression occured during the recent codegen work.
