Summary: HEAP_ValidateInUseArena memory tail overwritten when
                    updating Wine
           Product: Wine
           Version: 1.2-rc5
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs@winehq.org
        ReportedBy: hoehle@users.sourceforge.net
Both on Linux and MacOS I observed the following when Wine performs an update
with the memory fence turned on:
WINEDEBUG=warn+heap wine winecfg
err:heap:HEAP_ValidateInUseArena Heap 0x110000: block 0x111590 tail overwritten
at 0x1115b5 (byte 0/19 == 0x00)
err:heap:HEAP_ValidateInUseArena Heap 0x110000: block 0x1167a0 tail overwritten
at 0x1167ad (byte 0/11 == 0x00)
wine: configuration in '/Users/.../.wine' has been updated.
Reproduce after rm ~/.wine/.update-timestamp
On Linux the reported byte position is twice byte 0/11.
In addition, when gecko is present, there are 5 occurrences of
warn:heap:validate_block_pointer Heap 0x110000: pointer 0x40248080 is not
inside heap
(as it's the same heap address it could be the same bug).
