Work_issues: segfault of div of Laurent series |
-------------------------------------------------+--------------------------
Comment(by SimonKing):
The segfault problem seems to come from the fact that the div method for
Laurent series relies on the div method for power series -- and with my
patch, the div method for power series uses the div method for Laurent
series. Not good. But that seems solvable.
