I found a problem with normal() which did not exist in older versions of GiNaC, but I have not found out yet when exactly it broke:
I tried several old versions, and it seems that this bug has been present for quite a long time, since end of May. On May 28, it still worked. On May 29, 30 and 31, the test produces a division by zero error Beginning with Jun 01, normal() does not work as expected. The division by zero problem was probably introduced by a change in numeric.cpp, checked in May 28 18:59, and fixed May 31 18:24, the only other files which changed were normal.h and normal.cpp, checked in May 31 18:24 and 19:00 resp. -- Alexander Frink E-Mail: Alexander.Frink@Uni-Mainz.DE Institut fuer Physik Phone: +49-6131-393391 Johannes-Gutenberg-Universitaet D-55099 Mainz, Germany
