Your /usr/local/bin/vim is stripped, so we don't see function names or line numbers.
Install vim unstripped by uncommenting this line in vim/src/Makefile:

STRIP = /bin/true

Alternatively run valgrind with the vim in the vim/src/ directory (that one is not stripped).

Looking at your valgrind file, I see that NULL is referenced, causing segfault.
