I am working on a SUN3 under SUNOS4.0.3 with gcc 1.36 and g++ 1.36.1.
I tried to install libg++ 1.36.1 with the result that the sun assembler
complains of invalid operands. The minimal program with the same behavior
follows:

-------------------------

// file: dings.cc

struct foo {
  foo () {}
} bar;

-------------------------

The compiler is called via:

-------------------------

g++-1.36.1 -v -g -c dings.cc
gcc version 1.36.1 (based on GCC 1.36)
 /gmdusr/g++/lib-1.36/gcc-cpp -+ -v -undef -D__GNUC__ -D__GNUG__ -D__cplusplus -Dmc68000 -Dsun -Dunix -D__mc68000__ -D__sun__ -D__unix__ -D__HAVE_68881__ -Dmc68020 dings.cc /usr/tmp/cca02516.cpp

 /gmdusr/g++/lib-1.36/gcc-cc1plus /usr/tmp/cca02516.cpp -quiet -dumpbase dings.cc -g -version -o /usr/tmp/cca02516.s
GNU C++ version 1.36.1 (based on GCC 1.36) (68k, MIT syntax) compiled by GNU C version 1.36.
default target switches: -m68020 -mc68020 -m68881 -mbitfield
 as -mc68020 -o dings.o /usr/tmp/cca02516.s
as: error (/usr/tmp/cca02516.s:53): Invalid operand

The generated assembler code is:

The assembler complains about the last .stabs instruction.


Does that mean that I have to use the gas assembler or is this a real bug?
