[Bug nptl/22563] __cancel_jmp_buf in __pthread_unwind_buf_t is incompatible with setjmp/longmp


https://sourceware.org/bugzilla/show_bug.cgi?id=22563

--- Comment #4 from H.J. Lu <hjl.tools at gmail dot com> ---
/* Internal version of the buffer to store cancellation handler
   information.  */
struct pthread_unwind_buf
{
  struct
  {
    __jmp_buf jmp_buf;
    int mask_was_saved;
  } cancel_jmp_buf[1];

has the same issue.
