This is the issue I mentioned in https://trac.sagemath.org/ticket/29240#comment:3 For some time I could reproduce it on sage-the-distro but not on my Arch package, then I could no longer reproduce it on sage-the-distro and suddenly started happening on the Arch package, triggered by the sympy 1.6.1 update (which shuffles some imports). It seems that the singular instance is being unloaded from memory, which causes pexpect to crash. While trying to debug this, I found that removing almost *any* test block from singular.py will prevent it from crashing, which is certainly weird.
