Rrr... I'm in the same area. The problem is getrpcport() (that's buried
inside get_yp_master()). getrpcport calls gethostname(), and I think
it's gethostname that's clobbering memory somehow. This is something I
stumbled onto a long time ago. I thought I had worked around it, but
apparently I was wrong. I never did figure out why gethostname() was
zonking my pw structs, so I avoided calling gethostname() until after
I had copied it.

The weird thing is: I just linked a static version of chpass for testing
and _that_ executable works. This is damn strange. I'm starting to wonder
if maybe there's a deeper problem somewhere.
