I cannot reproduce this on the devel branch. It looks like it was fixed by 6711d2dc7793ed3d35e91b2bd4ecbdfccfcf469f (so between the release of 5.2.2 and 5.2.3), but that fix has not been officially released as a patch for bash 5.2. https://git.savannah.gnu.org/cgit/bash.git/commit/?h=devel&id=6711d2dc7793ed3d35e91b2bd4ecbdfccfcf469f It is caused by the same bug that was causing this other issue: https://lists.gnu.org/archive/html/bug-bash/2022-10/msg00098.html emanuele6
