# 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.
