On my ARAnyM setup, I have g++ 2.95.3 and binutils 2.18.
I reproduced more or less the same bug as you. Instead of displaying the
substring, the programs displays the whole memory, so obviously the
string we want to display contains a bad pointer. That looks like a g++
bug, they are usually very hard to isolate (and I'm not going to spend
my time on gcc 2.95.3).

Personally, I feel very comfortable with cross-compilation. From
Windows, you can edit your C/C++ programs with Visual Studio, then
compile in a Cygwin window, and if your build dir is mounted in the
ARAnyM filesystem, you just have to do Alt+TAB to switch to ARAnyM and
run your program inside TOSWIN/bash.
Furthermore, a cross-compiler running on a supported gcc host (Cygwin or
Linux) has potentially less bugs than a native gcc running on
unsupported host (MiNT). Hopefully, compilers use very few system
functions (mainly file I/O), so the potential bugs due to the
unsupported host are somehow limited.
The problem is that we didn't manage to make a clean native build of GCC
4.X, with RPM packages. Some experimental binaries have been built by
some people. As far as I remember, MiKRO managed to build a native gcc
4.3.2 on 04/10/2008. He will certainly share his binaries with you if
you want to experiment.
Note: the problem with the gcc is the size of its sourcecode. It takes
literally hours to build a cross-compiler on a recent machine. For
building it from ARAnyM, it takes more, more time... So debugging the
build scripts and fixing build problems requires to have a huge amount
of time and patience.
