We have:
short last[3] = { 16,16,16 }, mul[3], buf[3][3][386];
for (i=0; i < sizeof(buf)/sizeof(short); i++)
buf[0][0][i] = 2048;
Obviously this where one of the warning happens.
Likewise for:
float cfilt=0, ddft[3][3][2], ppm[3][3][3];
>For one, the compiler considers it an issues that array cam_xyz[4][3] is
accessed as cam_xyz[0][j], 0 <= j < 12. This issue is found with -O3 but not
with -O2.
That warning is correct. Now for the other part, this warning really depends
on optimization and is not always 100% of producing all the warnings it could.
