Not sure if the compiler is correct here, but maybe worth a look:
hash.c:549:11: error: implicit conversion from 'unsigned long' to
'float' changes value from 18446744073709551615 to 18446744073709551616
[-Werror,-Wimplicit-int-float-conversion]
if (SIZE_MAX <= new_candidate)
^~~~~~~~ ~~
/usr/include/stdint.h:227:22: note: expanded from macro 'SIZE_MAX'
# define SIZE_MAX (18446744073709551615UL)
^~~~~~~~~~~~~~~~~~~~~~
hash.c:1079:15: error: implicit conversion from 'unsigned long' to
