I have to add a comment: all those crashing KDE applications (I looked at the
KDE PRs) are evidently using mt_allocator. Now, mt_allocator is not the alloc
which FSF gcc4.0.x uses by default, the only one for which ABI guarantees are
provided, also about compatibility with gcc3.4.x. I gather therefore that
is building GCC passing --enable-libstdcxx-allocator=mt, something absolutely
not obvious and not trivial in its consequences.
