This crash disappered when I revert r32071.
But instead, following test failure was shown.

Sorry for late response.

I've reduced reproducible script at x86_64-darwin10.8.0 as follows.

require "coverage"

GC.stress = true

Coverage.start
Coverage.result
p [0]
Coverage.start
Coverage.result

I'll try to investigate this issue.
