#14189: Silence implicit uint64_t to size_t conversion warnings in clang on 32-bit
OS X

     Type:  defect  |         Status:  new
 Priority:  normal  |      Milestone:  Tor: 0.2.6.x-final
Component:  Tor     |        Version:  Tor: 0.2.6.2-alpha
 Keywords:  clang   |  Actual Points:
Parent ID:          |         Points:
--------------------+------------------------------------
 The out of memory checking code performs a calculation based on the
 difference between the memory used (a `size_t`) and the memory limit (a
 `uint64_t`).

 This causes warnings in clang about implicit conversions losing precision.
 To ensure this isn't happening, I assert `MaxMemInQueues <= SIZE_T_MAX`
 before casting.

 Branch will be posted after I have the bug number.
