  24 # When SIGFPE happens, the operating system may restart the
  25 # offending instruction after the signal handler returns,
  26 # rather than proceeding to the next instruction.  This happens
  27 # on i686-pc-linux-gnu with a linux kernel.  If gdb has a naive
  28 # signal handler that just returns, then it will restart the
  29 # broken instruction and gdb gets an endless stream of SIGFPE's
  30 # and makes no progress.
  31 #
  32 # On a broken gdb this test will just time out.
