Hi all,

I have an intermittent problem with PFBB_POINT_ROT_WORLD billboards which is
causing my application to crash with a Segmentation Violation - the stack
trace from dbx is included below.

Has anyone seen this before? Or does anyone have any suggestions where I
should start looking?

I'm running Performer 2.0 on IRIX 5.3 (Onyx RE).

Thanks,

Troy Stephen
