Research direction
Start by reproducing the issue with the unshare command shown in the report, using the coreutils yes command with stdout redirected to /dev/full and stderr closed. Trace how the command handles closed standard streams when /dev is masked; done means the same invocation does not terminate with SIGABRT.
