It's because getcontext is similar to setjmp.
Since setjmp/getcontext doesn't save registers in register window, modifications
to the registers between first setjmp/getcontext return and longjmp/setcontext
call is retained for second return from setjmp/getcontext via
longjmp/setcontext.
It seems that gcc knows setjmp is special but doesn't know about getcontext.
Note that getcontext is defined by Single Unix Specification.
