Confirmed. IPA-SRA generates this. # .MEM_9 = VDEF <.MEM_14> *ISRA.13_16(D) = *ISRA.12_2(D); if that's invalid gimple it means that the type is is_gimple_reg_type.
Right. IPA-SRA currently relies on that it can always replace a memory reference with a memory reference. But both sides of this assignment were originally one field structures turned into scalars and so the assumption does not hold. It seems I need to detect this particular case and handle at the same place where I fix types.
Created attachment 19197 [details] Simple testcase A simple test case that exhibits this bug and ICEs on both i386 and x86_64.
Created attachment 19198 [details] Patch dealing with such assignments I'm currently testing this patch to address the problem.
Ok if it passes.
