Hi,
I've updated to the latest HEAD and compilation with clang-16 and clang-17 and
./configure --enable-compiler-atomic-builtins --disable-legacy-mb
It fails with:
rculfhash.c:1189:2: error: address argument to atomic operation must be a
pointer to integer ('typeof (node_next)' (aka 'struct cds_lfht_node **')
invalid)
uatomic_or_mo(node_next, REMOVED_FLAG, CMM_RELEASE);

2 errors generated.
It works with gcc-12, so it seems that clang has stricter rules here.
