Which sync.c patch are you mentioning?

If it's my patch (sync.c 1.65-1.66), there's only one hunk
There's no compile fix in it, just a fix to avoid a segmentation fault.

If it's your patch, there are 3 hunks...
You're basically switching "j" and "k", and it fixes the issue by chance 
because you forgot to also switch "j" and "k" at line 159.
With your patch applied, at line 159, j->data has become a (pmpkg_t *) 
that will for sure never make strcmp return 0...

Anyway, I think the issue comes from the _alpm_depmiss_new declarations 
for CHECK3 that are switching tp->name and info->name.
I'm attaching a patch based on yours fixing that point.

Added to the TODO.
