 # test SIGFPE (such as division by 0) inside gdb itself
 
 
 gdb_start
 
 # When SIGFPE happens, the operating system may restart the
 # offending instruction after the signal handler returns,
 # rather than proceeding to the next instruction.  This happens
 # on i686-pc-linux-gnu with a linux kernel.  If gdb has a naive
 # signal handler that just returns, then it will restart the
 # broken instruction and gdb gets an endless stream of SIGFPE's
 # and makes no progress.
 #
 # On a broken gdb this test will just time out.
