Do you mind doing a bit of detective work, and going through
src/sna/gen3_render.c and disable each sse routine individually, like:

diff --git a/src/sna/gen3_render.c b/src/sna/gen3_render.c
index 59d13db..fd7c13d 100644
--- a/src/sna/gen3_render.c
+++ b/src/sna/gen3_render.c
@@ -3666,7 +3666,7 @@ gen3_render_composite(struct sna *sna,
                case SHADER_WHITE:
                case SHADER_CONSTANT:
 #if defined(sse2) && !defined(__x86_64__)
-                       if (sna->cpu_features & SSE2) {
+                       if (sna->cpu_features & SSE2 && 0) {
                                tmp->prim_emit =
gen3_emit_composite_primitive_c
                                tmp->emit_boxes =
gen3_emit_composite_boxes_cons
                        } else

Then when you find the one that is responsible for the error, please let me
know and please attach your src/sna/.libs/gen3_render.o
