Reproduced with '--buildtype=debugoptimized' config,
compiler version: gcc (GCC) 12.0.0 20210509 (experimental)
There are multiple build errors, like:
../drivers/net/ice/base/ice_switch.c: In function ‘ice_add_marker_act’:
../drivers/net/ice/base/ice_switch.c:3727:15:
warning: array subscript ‘struct ice_aqc_sw_rules_elem[0]’
is partly outside array bounds of ‘unsigned char[52]’
[-Warray-bounds]
3727 | lg_act->type = CPU_TO_LE16(ICE_AQC_SW_RULES_T_LG_ACT);
| ^~

from ../drivers/net/ice/base/ice_switch.c:5:
../drivers/net/ice/base/ice_osdep.h:209:29:
note: referencing an object of size 52 allocated by ‘rte_zmalloc’
209 | #define ice_malloc(h, s) rte_zmalloc(NULL, s, 0)
| ^~~~~~~~~~~~~~~~~~~~~~~
../drivers/net/ice/base/ice_switch.c:3720:50:
note: in expansion of macro ‘ice_malloc’
lg_act = (struct ice_aqc_sw_rules_elem *)ice_malloc(hw, rules_size);
These errors are mainly because allocated memory is cast to
"struct ice_aqc_sw_rules_elem *" but allocated size is less than the size
of "struct ice_aqc_sw_rules_elem".
"struct ice_aqc_sw_rules_elem" has multiple other structs has unions,
based on which one is used allocated memory being less than the size of
"struct ice_aqc_sw_rules_elem" is logically correct but compiler is
complaining about it.
Since the allocation is done explicitly and both producer and consumer
are internal, safe to ignore the warnings. Also to prevent any side
affect disabling the compiler warning for now, until proper fix done.
Reducing the warning disable to gcc >= 11 version.
