I wonder if the attached (untested) patch wouldn't fix this problem.

Sounds like a cprop_hardreg bug. Before that pass we have (after a call_insn):

So it is wrong already before *.alignments, as it has stuff like:

This one actually shouldn't be IMHO delegimized, the setm44 value is just a
temporary and thus it shouldn't hold any value interesting for debug info.
Can you please attach -fdump-rtl-vartrack dump?

That would be a target bug then, something isn't delegitimized when it should.
Please put a breakpoint on output_operand_lossage and print a backtrace and the
rtx that is being printed.
