    lib/libc/i386/gen    setjmp.S 
  Log:
  \begin{quote}
  setjmp() gets the jmp_buf pointer from the wrong place (the place
  where the return address is) in the shlib case, and uses it (only)
  to fetch the current signal mask to address (return_address + 28).
  This address is normally read-only (I hope), so the sigprocmask()
  call has no effect except to return an error code.
