Bug in G++

[Tom Haywood <thomas_haywood at aus dot hp dot com>]

Hello,

I have found in a bug in the c++ compiler of egcs-1.1.2. It is easily
reproduced and I have attached the 11 lines of code need to do so.
For reference this bug also occurs using gcc-2.8.1 for the same target,
which is SH. To check if it is target dependent I built egcs-1.1.2 for
HPUX 10.2 and found that the bug does not occur on the PA-RISC target.

Regards,

egcs version   : 1.1.2
Host system    : HPUX 10.2 (also occurs when hosted by Cygwin B20).
Target sytsem  : sh-elf (Hitachi SH, ELF, no OS on target).
Options passed : -c

Cut down version of code is as follows:

-----------------------------
class Base
{
public:
    Base(const Base& y);
    ~Base();
};

bool foo(Base prm1)
{
    return false;
}
-----------------------------

Command line for executing egcs is as follows:

% sh-elf-gcc -c ~/bug.cc
