It was on my 1.8 GHz Core 2 Duo laptop. I ended up able to compile it by putting my laptop next to a large fan, but it was pretty ridiculous. The worst part was that I had to perform this whole song and dance just because I wanted to change some key bindings. (Using Alt+number to change between tabs like every other Linux program.)

This serves as a nice textbook example of why implementing things like menus and keyboard shortcuts by hardcoding keycodes in C++ is a horrible idea.
