Question

I am using the md5.c file in an iOS app.
http://opensource.apple.com/source/cvs/cvs-33/cvs/lib/md5.c?txt

When I compile, I get the error:
Argument to ‘sizeof’ in ‘builtin_memset_chk’ call is the same expression as the destination; did you mean to dereference it?

This is in the line that is:
memset(ctx, 0, sizeof(ctx)); /* In case it’s sensitive */

What needs to be changed?

Answer 1

I think the compiler is asking if you want to change that line of code to:

memset(ctx, 0, sizeof(*ctx));
