Speaking of reproducing the warnings, the CRAN checks pass -Wall
-Wstrict-prototypes -pedantic to the compiler, while on Rhub, only the
UB sanitizer is used without any statical analysis warning flags.

It may be possible to see the extra warnings if you set CFLAGS = -Wall
-Wextra -Wpedantic in ~/.R/Makevars.
