Functions
	BOOST_AUTO_TEST_CASE (RuleAreaDestroyedBeforeContainedItems)
	Verify that destroying a rule area before its contained items does not crash.
	BOOST_AUTO_TEST_CASE (ContainedItemsDestroyedBeforeRuleArea)
	Verify that destroying contained items before the rule area also works.
	BOOST_AUTO_TEST_CASE (CacheRefreshClearsReciprocalLinks)
	Verify that rebuilding rule area caches clears reciprocal links on owned children and directive labels which are no longer attached to the area.

Detailed Description

Regression test for issue 22822: crash when closing eeschema while background library loading is in progress.

The crash occurs in SCH_RULE_AREA::RemoveItem() because FreeDrawList() deletes items in arbitrary order. If a rule area is destroyed before items it contains, those items' destructors call RemoveItem() on freed memory.

BOOST_AUTO_TEST_CASE() [1/3]

BOOST_AUTO_TEST_CASE

(

CacheRefreshClearsReciprocalLinks

)

Verify that rebuilding rule area caches clears reciprocal links on owned children and directive labels which are no longer attached to the area.

Definition at line 114 of file test_sch_rule_area_destruction.cpp.

BOOST_AUTO_TEST_CASE() [2/3]

BOOST_AUTO_TEST_CASE

(

ContainedItemsDestroyedBeforeRuleArea

)

Verify that destroying contained items before the rule area also works.

The reverse ordering should also be safe since SCH_ITEM::~SCH_ITEM calls RemoveItem on still-valid rule areas.

Definition at line 85 of file test_sch_rule_area_destruction.cpp.

BOOST_AUTO_TEST_CASE() [3/3]

BOOST_AUTO_TEST_CASE

(

RuleAreaDestroyedBeforeContainedItems

)

Verify that destroying a rule area before its contained items does not crash.

This reproduces the exact destruction ordering that caused the issue 22822 segfault in FreeDrawList().
