      This bug is not directly CRaC-related but was introduced with CRaC.

      In `DefNewGeneration::compute_new_size` `os::cleanup_memory` is called multiple times. If Eden is close to being full (top is within the last page), aligning the addresses leads to invocation of `os::uncommit_memory` with zero size, failing an assertion.
