A debugger as in gdb, VisualStudio etc.

You could just try updating to a more up to date version of the OSG, 2.8.1
is pretty ancient.  OSG-3.2.x is a better bet alround.  I have no clue
whether it will have any baring on the floating point error.

Again.  A stack trace is required.

Also info on hardware + GL drive would be useful as it could well be a
driver bug.
