[Mesa-dev] segfault in pstip_bind_sampler_states

[Kevin H. Hobbs]

One of the VTK tests (vtkFiltersHybridPython-largeImageOffset) makes
OSMesa segfault.

This is the top of the gdb backtrace :

#0  pstip_bind_sampler_states (pipe=<optimized out>, num=0, sampler=0x0)
at draw/draw_pipe_pstipple.c:713
#1  0x00007fffdf7580fc in cso_release_all (ctx=ctx at entry=0x15f1540) at
cso_cache/cso_context.c:307
#2  0x00007fffdf6aebad in st_destroy_context (st=0x15da330) at
../../src/mesa/state_tracker/st_context.c:287
#3  0x00007fffdf888022 in OSMesaDestroyContext (osmesa=0x13622d0) at
osmesa.c:583
#4  0x00007fffdcc02c13 in
vtkOSOpenGLRenderWindow::DestroyOffScreenWindow (this=0xec6770) at
/home/kevin/kitware/VTK/Rendering/OpenGL/vtkOSOpenGLRenderWindow.cxx:226

Do I interpret that as pstip_bind_sampler_states was sent a null pointer
sampler?
