When loading a game in The Witcher 3, the game crashes.

keep_for_full_loop = true
enclosing_scope = 0x7f8ff7beb0c0
enclosing_scope_first_read = 0x7f8ff7beb0c0
enclosing_scope_first_write = <optimized out>

keep_for_full_loop = <optimized out>
enclosing_scope_first_read = <optimized out>
enclosing_scope_first_write = <optimized out>
conditional = <optimized out>
enclosing_scope = <optimized out>
I used MESA_SHADER_DUMP_PATH to dump the shaders, and attached the last one in
chronological order (I assume this is probably the one that crashed).
