Anything interesting about where the crashes occur - in the lwp
functions themselves (savecontext, etc.) ?  and does it crash every
time it is switching lwps or are these sporadic?

One thing that might be worth trying is to see if switching to
setcontext/getcontext helps (see platforms that define USE_UCONTEXT),
if available, since it avoids the ugly manipulation of stack pointers
where maybe clang is doing something different..
