Fixed I suppose (looking at gcc-testresults).

Adding "--param sra-max-structure-size=32" solves the problem on
powerpc-apple-darwin9 at both -m32 and -m64 as well.

Adding "--param sra-max-structure-size=32" as suggested in comment #1 makes the
test pass on powerpc64-linux with -m32 and -m64.  Jan, is that an appropriate
fix/workaround?

A couple of issues here:
    nasty_local.a = nasty_local$a;
is a SRA issue and that should not be needed.

The rest is just SRA not doing element copy for the struct (it is not a big
issue) and the testcase should just include "--param sra-max-structure-size=32"
because what it is testing is that SRA can do the element copy with the removal
of memcpy.
