19 # test SIGFPE (such as division by 0) inside gdb itself
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.
32 # On a broken gdb this test will just time out.
