I ran this example for about an hour without any crash using revision 5b53cb580. So without any further info on your revision, configure options, ... I can't help.

Resolution: not a bug
Status: newclosed

comment:3 Changed 9 years ago by kroeker@…

if I recall correctly, it was a segfault, solved by a different bugfix. Now, the example finishes or does not finish, depending on used environment(hardware+software)

I will investigate and in case of new insight (re)open the issue.

This was a reported segfault which was not possible to reproduce (under a lot of test environments) The original reported failed to provide additional information within the last 6 month.
