[pdf-devel] FS#103: Possible memory overflow in the bignums implementation

[Miguel Angel]

In "pdf-types.h" I see at least one error (if you test before calling
"pdf_i64_div" that divisor isn't 0, like in "pdf_i64_mod"):
>#define pdf_i64_div(dest, dividend, divisor, p_status) \
>  do                                                   \

If there isn't destination because it's NULL, why you store on it the
result? This line shouldn't be in the else clause?

I hope that help you.

Happy hacking:-)
