Yes, mn10300 and h8300 compilers tend to give false positives for them.

Since I know you like fixing these warnings ;-), here's the full remaining list
(ignoring mn10300 and h8300) for v3.10-rc1:

argument of type 'long unsigned int', but argument 2 has type
'resource_size_t' [-Wformat]: 2 warnings in 2 logs
