Piglit `getactiveattrib 110` test started to randomly fail on llvmpipe:
$ for i in `seq 1 100`; do .../piglit/bin/getactiveattrib 110 -auto -fbo; done
PIGLIT: {"result": "pass" }
PIGLIT: {"result": "pass" }
PIGLIT: {"result": "pass" }
PIGLIT: {"result": "pass" }
PIGLIT: {"result": "pass" }
PIGLIT: {"result": "pass" }
PIGLIT: {"result": "pass" }
PIGLIT: {"result": "pass" }
Mesa: User error: GL_INVALID_VALUE in glGetActiveAttrib(index)
Failing shader:
attribute vec4 vertex;
attribute vec2 alternate;
uniform bool use_alternate;
void main() {
gl_Position = vertex;
if (use_alternate) gl_Position = alternate.xyxy;
}
Attribute `alternate' listed multiple times in active list.
PIGLIT: {"result": "fail" }

And likewise, if I revert a563689 it passes consistently.
