[osg-users] Mac OS X 10.5 crash in osgText

I seen some other threads mentioning FreeType not being thread save. 
This is OSG 2.6 branch

This is replicable with plain osgviewer on OSX  on a MBP 2.4

To replicate:

export OSG_WINDOW='20 20 800 600'

open osgviewer cow.osg

press 's' to show the stats

with '<' and '>' go up and down the window resolutions ...

it crashes always at the same point ... see below

Is there any solution? If so will it be backported to 2.6?

Cheers,
Hartmut
