Objects of type ucontext_t cannot be copied, only getcontext can
properly initialize them. For example, on powerpc the structure
contains a pointer into itself, so makecontext modifies the original
object by side effect.
The terminal output etc is not visible in a core file. The new
libc-internal variable __abort_msg will point to a string with the
message which has been printed before the abort in case abort is
called from inside libc. BZ #10217
