| # 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. |
