Can be reproduced with "make EXTRA_CFLAGS='-O1'" command using gcc (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2) Two build errors: 1) In file included from .../build/include/rte_ring_elem.h:1093, from .../lib/librte_rcu/rte_rcu_qsbr.c:21: ../lib/librte_rcu/rte_rcu_qsbr.c: In function ‘rte_rcu_qsbr_dq_reclaim’: .../build/include/rte_ring_peek.h:282:22: error: ‘avail’ may be used uninitialized in this function [-Werror=maybe-uninitialized] 282 | *available = avail - n; | ~~~~~~^~~ ./build/include/rte_ring_peek.h:259:11: note: ‘avail’ was declared here 259 | uint32_t avail, head, next; | ^~~~~ 2) In file included from .../build/include/rte_ring_elem.h:1093, from .../build/include/rte_ring.h:405, from .../app/test/test_ring_stress.h:13, from .../app/test/test_ring_stress_impl.h:5, from .../app/test/test_ring_peek_stress.c:5: .../app/test/test_ring_peek_stress.c: In function ‘_st_ring_enqueue_bulk’: .../build/include/rte_ring_peek.h:80:22: error: ‘free’ may be used uninitialized in this function [-Werror=maybe-uninitialized] 80 | *free_space = free - n; | ~~~~~^~~ .../build/include/rte_ring_peek.h:60:11: note: ‘free’ was declared here 60 | uint32_t free, head, next; | ^~~~ The cases shouldn't be hit, and it looks like there is already logic error if it has been hit, but assigning 'avail' & 'free' to '0' to fix the build error.
