Speller week 5 Segmentation fault

Question

I can't understand where and what my error is I think it's because of "load", but I can't fix it

it returns an error when checking

:) dictionary.c, dictionary.h, and Makefile exist

:) speller compiles

:| handles min length (1-char) words can't check until a frown turns upside down

If the code doesn't compile for check50, none of the other tests will be executed. Did you change anything in speller.c, speller.h or dictionary.h? This will cause a compile fail because those files are not uploaded with dictionary.c. You should keep all the file mods to dictionary.c. Also, the function signatures in dictionary.c can't be changed either.

if this doesn't solve your problem, then please edit the question and post the full code.
