Ilya reported in issue #1816 a build warning on armhf (promoted to error here since -Werror): src/fd.c: In function fd_rm_from_fd_list: src/fd.c:209:87: error: passing argument 3 of __ha_cas_dw discards volatile qualifier from pointer target type [-Werror=discarded-array-qualifiers] 209 | unlikely(!_HA_ATOMIC_DWCAS(((long *)&fdtab[fd].update), (uint32_t *)&cur_list.u32, &next_list.u32)) | ^~~~~~~~~~~~~~ This happens only on such an architecture because the DWCAS requires the pointer not the value, and gcc seems to be needlessly picky about reading a const from a volatile! This may safely be backported to older versions.
