Comment(by jpflori):
So I'm finally having a look at that.
Here are some examples producing the bug or not:
{{{
sage: var('t')
t
sage: (x-t)^3
(-t + x)^3
sage: (-t+x)^3
(-t + x)^3
sage: (-x+t)^3
Program received signal...
sage: (t-x)^3
Program received signal...
sage: var('z')
z
sage: (-x+z)^3
-(x - z)^3
sage: (x-z)^3
(x - z )^3
sage: (-z+x)^3
(x - z)^3
sage: (z-x)^3
-(x - z)^3
sage: var('y')
y
sage: (y-t)^3
-(t - y)^3
sage: (t-y)^3
(t - y)^3
sage: (-y+z)^3
(-y + z)^3
sage: (y-z)^3
Program received signal ...
}}}
