------- Comment #21 from pinskia at gcc dot gnu dot org  2005-10-31 01:40 -------
Reproduced on the mainline on arm-elf using the testcase in comment #4 also so
changing Priority to P3 so that Mark knows that he has to recide this bug as
arm-elf is a primary/secondary target.

Seems to happen a lot on hppa-linux here.  19 packages fail to build due to
this.  Do you need another testcase?

------- Comment #24 from jason at gcc dot gnu dot org  2005-11-07 19:35 -------
This is a bug in the generic thunk support; it doesn't show up on x86 because
it uses asm thunks.  Continuing to investigate.

My earlier patch fixed all the reduced testcases, but not the unreduced one. 
Here's a reduced testcase that still fails (adding a by-value parm to the
virtual function):

struct A
{
  A(const A &a);
  const A& operator=(const A& a);
};

struct B
{
  virtual A f(A);

I can't duplicate this problem using either the original mcop testcase
or the reduced testcase.

Are you possibly trying to use the HP assembler?  If so, I suggest using
gas.  Also, make sure that you have a recent linker patch installed.  You
will get segementation faults linking if the linker isn't updated.  There
will also be problems with constructors.  The HP assembler doesn't have
weak support.

------- Additional Comments From mki at maconomy dot dk  2005-07-15 19:11 -------
I'm using gas from binutils-2.16. But the ICE seems to appear before as is run
at all (If the cc1plus command succeeds it will be followed by
"/usr/local/binutils-2.16/bin/as -o trauscher.o trauscher.s"). The linker can
thus not have any influence either. IMHO ;-)

When I'm testing trauscher's example I get the following output, which says
"something" about my setup. (11.11 with PHSS_30970 installed).
Dave, how does your working configuration look like?

I wasn't implying that either the linker or the assembler are directly
involved.  The choice of assembler when GCC is configured affects the
defaults for code generation.  In particular, when gas is used, there
is support for one-only in C++.

The setup appears fine.  I've enclosed mine below.

I wonder if this is a pch problem.

This might be a second-order code generation bug, when I build bootstrap on PA
HP-UX I get a GCC that has this problem but when I build all-gcc with GCC 3.4.2
and the -g option I do not see the bug.

Can you be more specific about the starting compiler when you see the
problem?

Not very enlightening.  I think the actual fault needs debugging
on a system that can reproduce it.

I did some more tests and it looks like --disable-checking also disables the 
bug. At least --enable-checking was enough to reproduce it. My latest 
configuration with this bug was

Hi,

Dave, you mentioned that it "needs debugging on a system that can reproduce it".
Is there anything I can do to debug it? It seems like you know what to look
for... Something like building gcc with -save-temps, once with
--disable-checking and once with --enable-checking, and find the difference in
.ii and .s files? What is the right way to do that?

I can't provide access to machine where it can be tested. Perhaps Steve@HP can?

I was just able to reproduce it using a cvs head build done yesterday.
It had checking enabled.  The release builds that I had tried previously
had checking disabled.  Thus, it looks as if the ICE is caused by a
tree check failure in the assert at cp/cp-objcp-common.c:101, rather
than the assert itself.

Actually, it's the enabling of assert checking that catches this
problem.

The problem can be duplicated with an x86 cross to hppa-unknown-linux-gnu.

$2 = void

"type" is record_type but CLASSTYPE_NON_AGGREGATE (type) is true, so
CP_AGGREGATE_TYPE_P is false.  It would appear that cp_expr_size shouldn't
be called in this situation...

The problem occurs on hppa-unknown-linux-gnu as well as hppa*-*-hpux*.
