            Bug ID: 59938
           Summary: HeapWalk() reports LFH groups as busy blocks
           Product: Wine
           Version: 11.11
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Our applications use HeapWalk() to report memory leaks
(PROCESS_HEAP_ENTRY_BUSY) but it seems that Wine reports blocks that are not
reported in Windows.

It seems to be caused by heap_walk_blocks() not checking for BLOCK_FLAG_LFH and
report such an LFH block itself with PROCESS_HEAP_ENTRY_BUSY. Instead the
actual blocks within the LFH blocks, if any, should be reported with
PROCESS_HEAP_ENTRY_BUSY.
