No, setjmp/longjmp must preserve the call-saved registers and it does in almost
all cases, both on Linux and Solaris. But you're clobbering the stack pointer
after calling setjmp and this cannot reasonably work on SPARC because of the
way setjmp/longjmp is implemented for this architecture.
Let's declare this as WONTFIX; you can use __builtin_setjmp/longjmp instead.
