            Bug ID: 102274
           Summary: assertion failure in ir_validate.cpp:240
           Product: Mesa

                OS: All
            Status: NEW

I think this is a recent regression but I haven't had time to bisect it yet.

The piglit tests fs-ldexp.shader_test and vs-ldexp.shader_test fail:

$ bin/shader_runner
tests/spec/mesa_shader_integer_functions/execution/built-in-functions/fs-ldexp.shader_test
-auto
shader_runner: ../../../src/compiler/glsl/ir_validate.cpp:240: virtual
ir_visitor_status {anonymous}::ir_validate::visit_leave(ir_expression*):
Assertion `ir->operands[i] == __null' failed.
Aborted
