Fixed
- With test groups and
threads-required, a test waiting for a slot in its group is now started as soon as enough threads are free. Previously, if the threads were freed by a test outside that group, the waiting test could be delayed. If no other test in its group was still running, the run could end with the test not being run. (#3697) - Fixed a panic when reusing builds (
--archive-fileor--binaries-metadata) for a custom target provided byrustc --print=cfg. (#3698)
