Chris,
We are curious what can be done about the performance regression one of
your patches for dummy index renaming introduced. The seemingly
innocuous patch has been identified by Jens and Alexei:
<http://www.ginac.de/pipermail/ginac-list/2007-September/001215.html>.
At first, the above log message suggested to me that the problem has
been dealt with. But that is not so: The program is still extremely
slow. In fact, Alexei's patches are entirely unrelated. Since neither an
explanation of what's happening nor a fix has been suggested, we would
really appreciate some expert insight by you.
Thanks in advance
-richy.
