dash version 0.5.11+git20210903+057cd650a4ed-3 in unstable disabled LINENO support, thus pam builds again and this bug is not severity "serious". Nevertheless, the patch should still be applied for when dash enables LINENO support in the future. To confirm the bug, build pam with dash from experimental which has LINENO support enabled.
