That works.

Sorry to be a pain, but can you explain how to compile without it?
Previously, I just took the debian package from unstable and compiled
it on my ubuntu machine. I took a quick look, but I couldn't convince
cmake to not add -O2 to the command line. Is there any documentation
on how to build gmsh?

Even if it works when compiled in a different manner, there might
still be a bug; it's just it happens to be overwriting memory
which isn't used later, or something else is different so that
it doesn't have any visible effects.

Cheerio
