15:49:55 [2024-04-22T19:49:55.165Z] ghprbPullLongDescription=If the [`findOrCreateTreeInfo`](https://github.com/eclipse/omr/blob/8037ccd0406c017f6a8043a8d04e19ac68f626f2/compiler/optimizer/DeadTreesElimination.cpp#L66) function fails to find a `TreeInfo` object that refers to a particular `TR::TreeTop` in the `targetTrees` `List`, it allocates a new `TreeTop` instance using `trStackMemory`.  However, `findOrCreateTreeInfo` is called within a call tree from [`DeadTreesElimination::process`](https://github.com/eclipse/omr/blob/8037ccd0406c017f6a8043a8d04e19ac68f626f2/compiler/optimizer/DeadTreesElimination.cpp#L759).  The `process` method [creates a new `TR::StackMemoryRegion`](https://github.com/eclipse/omr/blob/8037ccd0406c017f6a8043a8d04e19ac68f626f2/compiler/optimizer/DeadTreesElimination.cpp#L761) on entry to the method, but the `targetTrees` `List` has a lifetime that extends for the duration of the optimization.  (The `_targetTrees` is first constructed in the [`DeadTreesElimination` constructor](https://github.com/eclipse/omr/blob/8037ccd0406c017f6a8043a8d04e19ac68f626f2/compiler/optimizer/DeadTreesElimination.cpp#L435-L437) and is only cleared in the [`prePerformOnBlocks`](https://github.com/eclipse/omr/blob/8037ccd0406c017f6a8043a8d04e19ac68f626f2/compiler/optimizer/DeadTreesElimination.cpp#L477) method.\r\n\r\nThe `TreeInfo` objects should be allocated from the same `TR::Region` that the `List` uses for allocation of its nodes to ensure that their lifetime is as long as that of the containing `List` object.\r\n\r\nFixes:  Issue eclipse-openj9/openj9#19197
