Not AFAICS from what you pasted.  The print time outs seem to me to be
cascading fails.  Highlighting what you pasted:

  (gdb) PASS: gdb.base/exitsignal.exp: $_exitcode is void before running
  continue
  Continuing.

  Program received signal SIGSEGV, Segmentation fault.
  0x00003fffb7cbf808 in .raise () from target:/lib64/libc.so.6
  (gdb) PASS: gdb.base/exitsignal.exp: trigger SIGSEGV
  continue
  Continuing.
  FAIL: gdb.base/exitsignal.exp: program terminated with SIGSEGV (timeout)
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  print $_exitsignal
  FAIL: gdb.base/exitsignal.exp: $_exitsignal is 11 (SIGSEGV) after SIGSEGV. (timeout)
  print $_exitcode
  FAIL: gdb.base/exitsignal.exp: $_exitcode is still void after SIGSEGV (timeout)
  kill

  Program terminated with signal SIGSEGV, Segmentation fault.
  The program no longer exists.
  (gdb) print $_exitsignal
  $3 = 11
  (gdb) print $_exitcode
  $4 = void

That timed out waiting for the "Program terminated with signal SIGSEGV"
output.  Stripping the prints, we see it more clearly:

  Program received signal SIGSEGV, Segmentation fault.
  0x00003fffb7cbf808 in .raise () from target:/lib64/libc.so.6
  (gdb) PASS: gdb.base/exitsignal.exp: trigger SIGSEGV
  continue
  Continuing.
  FAIL: gdb.base/exitsignal.exp: program terminated with SIGSEGV (timeout)
  Program terminated with signal SIGSEGV, Segmentation fault.
  The program no longer exists.
  (gdb)

Thanks,
