Indeed, I expect that a bug like this would effect *anything* that involves writing to a positionable file. It's not clear to me from the discussion if this is a bug in the runtime C library, or in the gcc optimizer (sic). Is it the case that a pre-compiled VM that works properly on one Linux platform will have this bug if run on another Linux platform that has a different runtime clib? Or is it the case that a VM compiled from source on one platform behaves differently than the same VM compiled from source on a different Linux platform?
