Hi,
I have some code that relies heavily on lrcalc and when the input gets
more complicated it starts crashing. I managed to find the following
minimal code example that usually crashes Sage here (run it repeatedly if
it does not crash at once):
{{{
import sage.libs.lrcalc.lrcalc as lrcalc
def lrcalc_test():
a=lrcalc.coprod([5,4,3,2,1])
b=lrcalc.mult([3,2,0],[0])
c=lrcalc.coprod([0])
d=lrcalc.mult([3,2,0],[0,1])
}}}
I am using Sage 6.4.1 (with lrcalc 1.1.7) on Ubuntu 12.04 amd64.
The output of sage is attached.
