--- Comment #7 from Nicolai Hähnle nhaehnle@gmail.com --- Thanks for the additional info. Running llc on those shaders under Valgrind doesn't show anything either, but this may be a limitation of Valgrind in connection with LLVM's internal allocator.
That this is exposed by the game's operator overrides is curious. If the bisection result is solid, we can't put the blame on those overrides though.
