[osg-users] setMaxAnisotropy() Causes Segfault

I was told to ask here for help on this.

I'm receiving a SIGSEGV when texture->setMaxAnisotropy() is called.
According to the header file texture is:
osg::ref_ptr<osg::Texture2D> texture;

I'm not familiar with osg nor the code that causes it
so I hope, you can help me.

Thread 1 "fgfs" received signal SIGSEGV, Segmentation fault.
0x00007ffff73e1890 in osg::Texture::setMaxAnisotropy(float) () from ../../openscenegraph/lib/libosg.so.162
(gdb) bt full
#0  0x00007ffff73e1890 in osg::Texture::setMaxAnisotropy(float) () from ../../openscenegraph/lib/libosg.so.162

    at /games/flightgear-new/simgear/simgear/canvas/ODGauge.cxx:207

I did already a sanity check on the input to rule out any
unreasonable input values.

What can I do to find the issue?
