As reported on Ask
<https://ask.sagemath.org/question/39204/segmentation-fault-when-multiplying-by-variable/>,
the following computation causes a segmentation fault:
sage: P.<x> = GF(3)['x']
sage: var('a')
sage: sigma = 2*x+ 1
sage: a * sigma
According to my tests, the problem occurs when one multiplies a symbolic
expression by a non monic polynomial over a finite field, having at
least two terms. Note that converting the polynomial to SR beforehand
does not change anything.
I did not succeed in finding the origin of this bug, so help is welcome.
I've opened ticket #24072 <https://trac.sagemath.org/ticket/24072> for this.
Best,
Bruno
