Why does qsort work while bsearch causes a segmentation fault when they both have the same arguments?

char *word
...
qsort(dictionary, dictionarySize, sizeof(char *), dict_compare);

bsearch(word, dictionary, dictionarySize, sizeof(char *), dict_compare);

It works if I replace bsearch with manually stepping through the array. Any ideas?

is this your own implementation of these functions?

OP here

Turns out I had to use
bsearch(&word, dictionary, dictionarySize, sizeof(char *), dict_compare);

I don't even know why. In every example I've seen they didn't need to do that. What the fuck.

Because bsearch needs to manipulate the pointer.
If you'd look at the prototype of bsearch it's probably something like
bsearch(char **, ..)
You passed a char* where char** was expected.
Oh, and don't try char **word; bsearch(word, ..) it will not work.
In short, learn C and read the god damn documentation (if any) of the functions you are using.
