0001-intel-ir-Fix-invalid-type-aliasing-with-undefined-be.patch
Does it go away with the attached patch? I had it in a branch that was making
some unrelated changes which just happened to affect the order instructions are
emitted by GCC in the test_fuzz_compact_instruction() function, causing the bit
twiddling to be done after the clear_pad_bits() call which modifies the same
data through a pointer of different type, leading to undefined behavior. I had
seen this happen on GCC 7.
