[Visualpython-users] Visual 5 from cvs - segmentation fault

[LUK S. <shu...@po...>]

Hi,

I checked out vpython-core2 from cvs and it built fine in
debian/sid/amd64. However it seg faulted when I tried with the examples.
Here's a gdb backtrace when running the bounce example.

Please let me know what further information should I provide so that the
source of the fault can be traced.
