Re: debugging tmpdir-gcc.dg-struct-layout-1 failures

Jakub,
    Okay. I managed to get the testcase built but -DDBG at -m64
by just changing the ifdef for DBDG to an ifndef in the header.
The results on Darwin PPC are as follows...

Does anyone recognize any sort of pattern to these failures which might suggest why they
fail on Darwin PPC at -m64 and not on ppc64?
