partial gallium trace

Attaching the gallium trace (at least up until the crash).  I'm still looking
through it, but the 2 resources being sampled are:

3948 pipe_context::create_sampler_view(pipe = 0x01073190, resource =
0x03fe46b0, templ = {format = PIPE_FORMAT_R8G8B8A8_UNORM, u = {tex =
{first_layer = 0, last_layer = 0, first_level = 0, last_level = 0}}, swizzle_r
= 0, swizzle_g = 1, swizzle_b = 2, swizzle_a = 3}) = 0x03f72690 // time 9
3949 pipe_context::create_sampler_view(pipe = 0x01073190, resource =
0x02be7930, templ = {format = PIPE_FORMAT_R32G32_FLOAT, u = {tex = {first_layer
= 0, last_layer = 0, first_level = 0, last_level = 0}}, swizzle_r = 0,
swizzle_g = 1, swizzle_b = 4, swizzle_a = 3}) = 0x03fcb740 // time 7
