Hi, Thanks Harald. I see there are bugs open, but actually not that many, compared to other areas of the compiler :) I think the code I sent was not really covered in the testsuite, so I have committed it (after testing on x86_64-linux). https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=a54c71ccc24874ce79019b51150b3a00b7c785cd Best, FX
