Hey everyone,<br>
<br>
I think I ran into a regression in IPython 3.0 where whenever I
interrupt running code, the IPython console and kernel crash.
Probably the easiest way I know to reproduce this is:<br>
<font face="monospace">$ ipython console<br>
In [1]: for i in range(1000000):<br>
...: print i<br>
...:</font><br>
And then press Ctrl-C during execution.<br>
<br>
I expect that it will catch a KeyboardInterrupt exception and then
go back to an IPython prompt. However, instead it outputs:<br>
<font face="monospace">Out [1]: 1<br>
2<br>
<font face="sans-serif"><...></font><br>

If you suspect this is an IPython bug, please report it at:<br>
<a href="https://github.com/ipython/ipython/issues" target="_blank">https://github.com/ipython/ipython/issues</a><br>
or send an email to the mailing list at <a href="mailto:ipython-dev@scipy.org" target="_blank">ipython-dev@scipy.org</a><br>
<br>
You can print a more detailed traceback right now with "%tb", or
use "%debug"<br>
to interactively debug it.<br>
<br>
Extra-detailed tracebacks for bug-reporting purposes can be
enabled via:<br>
%config Application.verbose_crash=True<br>
$</font><br>
<br>
Dropping me back at the shell. This doesn't occur in just running
plain "$ ipython", so the kernel should have something to do with
it.<br>
<br>
I am running IPython 3.0 through Anaconda on CentOS 6.6.I hadn't
encountered this bug in IPython 2. Maybe other people can confirm if
it occurs for them. And if so, what additional info I would need to
file a bug report. Thanks!<span class="HOEnZb"><font color="#888888"><br>
