With Andrew's patch for 14272 I now get cc1plus ICEs in 64-Bit mode.
A reduced testcase is this, compile with -m64 -O0:

  struct locale
  {
    int i;
    ~locale();
  };
  struct basic_ios
  {
    locale getloc () const { }
  };
  void copyfmt(const basic_ios& __rhs)
  {
    __rhs.getloc();
  }

The error message is:

cc1plus -O0 -m64 -quiet io.cc
io.cc: In function `void copyfmt(const basic_ios&)':
io.cc:12: internal compiler error: in copy_to_mode_reg, at explow.c:675
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

   regards Christian

-O0?  Interesting.  Does this happen with a bootstrapped cc1plus?  We
don't run any of the tree-ssa passes at O0 yet.

Do you still get the error if you build cc1plus with the system
compiler?


Thanks.  Diego.

Does this code work on the mainline also?

If I compile a fresh non bootstrapped cc1plus with the host compiler
(gcc-3.2) it ICEs with and without Andrew's patch, i.e. these failures
are not related to Andrew's patch (as I already suggested in PR 14272).

Then this may be a problem we inherited from mainline at the last
merge.  I'm working on another mainline merge.  I'll see if this makes
it go away.

If it doesn't, we may be having a gimplification problem.  At -O0, just
about the only thing we do is gimplify and expand into RTL.


Diego.

The following hunk introduced into mainline by Mark is probably going to
fix this bug. Will bootstrap now. It fixes the bug for the non-bootstrapped
compiler.
