OK. Is there a strict requirement on limiting to 80 columns for code
including an error message string in glibc ? IOW:

  if (__rseq_abi.cpu_id != RSEQ_CPU_ID_UNINITIALIZED)
    __libc_fatal ("glibc fatal error: rseq already initialized for this thread\n");

or

  if (__rseq_abi.cpu_id != RSEQ_CPU_ID_UNINITIALIZED)
    __libc_fatal ("glibc fatal error: "
                  "rseq already initialized for this thread\n");

?

Thanks,

Mathieu
