Hi

Debian Stable's maxima 46 also shows the error:

0 jan@jan-latitude:~$dpkg -l maxima|grep ii
ii  maxima         5.46.0-11    amd64        Computer algebra system --
base system
0 jan@jan-latitude:~$maxima -q<test-taylor.mac

(%i1)
(%i2)
PQUOTIENT: Quotient by a polynomial of higher degree (case 2a)
 -- an error. To debug this try: debugmode(true);

Regards,
Jan
