Re: stackless core dump on Ubuntu 14

Hi Terrence,

I'm one of the Stackless developers. You didn't mention the Stackless =

version, architecture and - less important - compile time options. =

Without this information nobody can help you.

Then, please make sure to use the latest version of Stackless. You can =

get the source from www.stackless.org. We fixed quite a few segfaults =

over the time.

If the bug persists with the latest version, you can open an issue on =

bitbucket:
1. Get a bitbucket account and sign in.
2. Open a new issue on =

https://bitbucket.org/stackless-dev/stackless/issues?status=3Dnew&status=3D=
open

King regards,
   Anselm
