Comment (by vinc17):

 OK on both points.

 The bug is now fixed in the master branch, assuming that the mailbox size
 is less than twice the maximum signed offset, which is necessarily true on
 64-bit in practice. And on 32-bit, the mbox file has to be huge (more than
 1 GB), but this is controlled by the user and there may be other issues
 with such a huge mailbox on 32-bit (e.g. lack of address space or other

 So I suppose that this fix is sufficient in practice.
