I can reproduce a similar backtrace on radeon and r200 using neverball, which is
doing a rasterization fallback beacuse I'm running at 16bpp (no stencil).
Program received signal SIGSEGV, Segmentation fault.

For crashes involving the inputptr loop it is necessary to find and fix
the reason rather than just adding a guard. Presumably vptr is NULL
above, and the ctx=0x0 is just a gcc/gdb artifact.
