The build completes with -O2 but not with -O3. I'm light years away from even a basic knowledge of compiler technology, but I would have thought that if the compiler inlined something, there would be no reference for the linker to subsequently resolve. But, like I say, I'm light years... Anyway, since filing the bug report, I've built the package on my laptop, which has GCC 3.3.6 installed. In this case the build completes with -O3 optimisation. > I think the only way to fix this is to dig into the sources of aspell and see > if this is the case.

I did have a dabble with Borland C++ many years ago, but since then templates (and similar stuff) have been introduced and made the language too complex for me to be bothered.. > > It might be worth filing a bug with aspell and seeing what they can do with > it. > > That was my first port of call, but I got no response.
