Platform: Mac OS X 10.8.4 64-bit (latest release at time of posting)
Version: MacVim 7.4.9 (vim original (hg) or vim/gvim based on macvim sources)
Reproduction:
:call expand('a', 'p', 0700)
causes immediate bus error.
I can't reproduce it on my Linux x86_64 laptop.
But SIGBUS would happen for a misaligned memory access which is
problematic on some processors (SPARC, MIPS, ...) but not other
(x86...). That's probably why I don't see the bug.
Can you provide a stack trace with gdb and/or reproduce it with
valgrind?

Hmm, I couldn't reproduce it with just expand this time though now but
mkdir still crashes in f_mkdir. Stack below:
% gdb /Applications/MacVim.app/Contents/MacOS/Vim
(gdb) set args -u NONE -U NONE +'call mkdir(expand("abc", "p", 0700))'
(gdb) run
Error detected while processing command line:
Program received signal EXC_BAD_ACCESS, Could not access memory.
The second problem is easy to reproduce with ':call mkdir([])'.
Please see the patch below for a fix.
I have no idea about the initial problem though. I can't reproduce
it, and I don't see any obvious bug in the code.
Thanks for the fix. I'll check it out.
