WorkerDataArray leaks C heap memory for associated work items

    XMLWordPrintable

Details

    • gc

    Description

      Integer work items are not freed at deletion of a WorkerDataArray.

      This is problematic for weak reference processing via WeakProcessor::weak_oops_do() as it provides a temporary WeakProcessorPhaseTimes object, leaking a few 100 bytes per GC.
