[GiNaC-list] Bug in numer_denom?

Dear all, I think there is a problem with the numer_denom function with large polynomial fractions. I added "bug.txt" to the attachment, which is an input file for ginsh. Using the version of GiNaC shipped with current stable Ubuntu, I get the result "out-installed". Here, "/" is contained in numerator and denominator, which should not be the case, if I understood the functionality of numer_denom right. Using git version of GiNaC, I get "out-git.txt". Here, braces are used in numerator and denominator, which also seems strange to me. Do I understand something wrong or is this a bug? Best regards, Moritz Hahn
