DECstation 5000/260 MIPS R4400; NetBSD 1.6;
binutils 2.13.2.1
>Description:
g++ can't create working or use shared libraries.
Programs linked against such libraries will crash on loading with a segmentation
fault.
My test program compiled with 'g++-3.2 -o test test.cc':
#include <iostream>
main()
{
  std::cout << "Hello!\n";
}

Output of 'ldd test'
test:
        -lm.0 => /usr/lib/libm.so.0
        -lstdc++.5 => /usr/local/lib/libstdc++.so.5
        -lc.12 => /usr/lib/libc.so.12
        -lgcc_s.1 => /usr/local/lib/libgcc_s.so.1

Output of 'gcc-3.2 -v'
Configured with: ../gcc-3.2.1/configure --host=mipsel-dec-netbsd1.6
--program-suffix=-3.2 --with-ld=/usr/local/bin/ld
--with-as=/usr/local/bin/as

Output of '/usr/local/bin/ld -v':
GNU ld version 2.13.2.1

Output of '/usr/local/bin/as -v':
GNU assembler version 2.13.2.1 (mipsel-dec-netbsd1.6) using
BFD version 2.13.2.1

Output of 'gdb test test.core'
[...]
#0  0x5ffe5b30 in _rtld_relocate_objects () from /usr/libexec/ld.elf_so

Creating a statically linked version of this program works,
i.e. "g++-3.2 -static -o test test.cc" produces a working
'test' program.

The same problem occurs with binutils 2.11.2.
binutils 2.9.1 can't be used for compiling gcc 3.2.1 on
mipsel as this will lead to an assembler error during
compilation of one of the libgcc files.

I tried g++ 3.2.1 on a SUN 4/260 (sun4) with SunOS 4.1.1
and it is broken too. gcc 3.2.1 however works fine on all
platforms.
