Multiple possibilities

- Both graph and crt might interfere both try to capture output. (graph via
linking in svgalib?)
- The console you use might also matter. Is it framebuffer, normal console,
    a terminal emulation under X?

Try to reproduce the problems with a small program using Crt only on a normal
(non X console).
