calling setjmp through a pointer

Greetings!  It appears that on sparc alone, I cannot call setjmp
successfully via a pointer to an address returned by dlsym within the
libc.so map.  Calling the .plt address appears to work fine.  What can
be going on here?

(by successfully, I mean that registers are not restored when returning
from a longjmp...)
