That is my guess. What do you understand from the gdb output? Do you have a recommendation?
>Why, exactly, do you need gcc-4.1?
We have a simulator which is old. I can fix the compiler errors under gcc 4.4 for the code *itself*. However the code uses boost 1.33.1 and this version of boost won't compile on gcc4.4.
Since I am not familiar with the complex structure of boost, at this time I have to find a way to *just* run the code.

I see you put it in /opt/. *Good*, keep it out of the dfault /usr/bin
or /usr/local/bin locations.

Good luck with that, it's a *lot* of work and likely to cause
conflicts with tyour gcc-4.4 components. You can put them in /opt if
you like. But why, exactly, do you want to do this?

libgcc and compat-gcc-34 are built from gcc source code, as part of
building up all of gcc.
Why, exactly, do you need gcc-4.1?
