[osg-users] DXF file with text crashes on Intersect

[Robert Osfield]

Hi Brian,

Please update to 3.6.1.  There are many improvements between 3.5.6 dev
release and the latest stable release, in particular to osgText so
while I can't say specifically that the issue you have come across is
fixed, there is a good chance.  There are also so many other
improvements that it's worth having for it's own sake.

If the problem still exists then an example that reproduces the issue
would be really helpful.

Robert.
