I've tested this with Mesa 743e11c10b from week ago and Mesa 233718a199 from today (I haven't tested 18.04 build earlier, so I have no idea whether this is a regression). GL & GLES versions of Aztec Ruins works fine, so the issue is Anvil specific. I've tested this on HSW & BXT and it happens on both, so I think it's a generic issue. (I got same result also from another GfxBench build, with a different backend, on Clear Linux / Wayland instead of Ubuntu 18.04 / X, when using same Mesa build.) Gdb output seems to validate that type used here is indeed sampler ("_sampler2DShadow_type"):Ģ08 src/compiler/nir/nir_opt_large_constants.c: No such file or directory.ī = I assume it's unreachable that's directly triggering the stack smash, instead of this being a stack corruption that could have happened elsewhere. Unreachable("type does not have a natural size") Other archs work as they different host libc is skipped. Glsl_get_natural_size_align_bytes(const struct glsl_type *type, stack smashing detected when using glibc For some reason QEMU / glibc x8664 picks up the host libc, which breaks things.
