[osg-users] [Crash issue] no error info even set "OSG_NOTIFY_LEVEL" to "DEBUG'

[Robert Osfield]

Hi Jinh,

osg::Notify has no relation to the stack traces, it's simply debug
output to help track what is being done by the OSG, it may sometime
pick out an issue that eventually causes a crash, but it's really
nothing more as info system.

As to the cause of the crash, there is no way for use to know at this
point - you are the only one with your particular combination of OS,
hardware, OSG version+build, application and data.  The best we can do
is provide general suggestions about how to debug C++/graphics
applications.  It'll be easier for us to comment if you give us more
info.

Robert.
