Assertion failure in RCHeader.decRC, #2

Description

The failure is in the same place as the one from but it only seems to occur on x64. However, we currently don't test GenRC on PPC64, so it might be a general 64-bit issue.

I've seen this failure on the actors benchmark multiple times. A recent report is at https://jikesrvm.anu.edu.au/job/x64-porting-main-repo/694/testReport/%28root%29/actors/actors__BaseBaseGenRC___default____Tests__scalabench_/ .
