comparison of integer expressions of different signedness: ‘size_t’ {aka ‘long unsigned int’} and ‘long int’ [-Werror=sign-compare]
This is asserting
end >= haystack
as a precondition for callers (in debugbuilds) and existing callers are correct.
An alternate option is to cast the left side to
int64_t
, but that may beslightly inefficient for 32-bit builds (to account for >=2GB strings).
Noticed when locally developing with
-Werror
