Tried something slightly different: because this happened in C++, I
bootstrapped
gcc-4.1.2 with lang=C,ada and it worked fine, error-free, including passing the
stage2 comparison passed. The resulting gcc-4.1.2 should now be enough to use
as base compiler to build everything else, including c++.
When doing this (same flags and options), I got exactly the same internal
compiler error again. Thus, both the base compiler gcc-3.4.3 and gcc-4.1.2 lead
to the same error.
Will try next without -O3 and other flags to see if one of these generate the
error.
