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.

Function Documentation

BOOST_AUTO_TEST_CASE() [1/2]

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.

BOOST_AUTO_TEST_CASE() [2/2]

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().
