both will trigger warnings for the same reason
(-Wincompatible-pointer-types-discards-qualifiers)
with Apple LLVM version 10.0.1 (clang-1001.0.46.4)
gcc-9 in macOS triggers 2 "warnings"; one for discarding the const
qualifier (-Wdiscarded-qualifiers)
and another for mismatching parameter to free():
note: expected 'void *' but argument is of type 'const uint8_t *' {aka
'const unsigned char *'}
Carlo
