A test worker crashed. It might be an interpreter bug or
a bug in test/unit/parallel.rb. Try again without the -j
option.
make: *** [uncommon.mk:965: yes-test-all] Error 1
In Immix, when a block is added into ImmixSpace::reusable_blocks during Block::sweep(), it is always set to BlockState::Reusable.
So far I have not been able to reproduce this bug locally. It may be related to the PR #113 I will try to restart the CI test to see if it can be reproduced on GitHub CI.
