I got the same ICE while trying to bootstrap gcc-4.8-20121021 for
x86_64-w64-mingw32.  gcc-4.8-20121014 bootstrapped Ok so this is a recent
regression.

may be this bus same as http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54957
there have a path in that post can solve this bug.

Indeed it does.  Thanks.

Fixed by r193052, aka PR54957.  However, testing is now made more difficult due
to r193032, aka PR52015 -- apparently one now needs bleeding edge mingw-w64
headers to build gcc-4.8 for x86_64-w64-mingw32.

it is actual not a target issue.  it is more a general c++ issue as
calling-convention (call-abi attributes) aren't part of signature.

Re-tested this testcase.  Seems to be fixed with current trunk.  With older
revision it failed as described.
I close this as worksforme.
