Anyway, I have debugged some more. Turns out the error in sid is still present, it just doesn't cause a crash. I have forwarded upstream to the above url. The error is not due to the macro, but due to the 3/2 p7. This is invalid syntax, and that triggers the crash/malfunction (the crash is in the error printing code, heh). You can work around the problem by fixing the syntax error and passing 1.5. -- Saludos, Felipe Sateler
