If this is a known bug, I've not been able to find a solution. Please advice.

I get this error:

Process Sage illegal instruction: 4

when I run this code:

from matplotlib import rc
g=Graph({1:[2,3], 2:[1,3], 3:[1,2]});

It used to run. This is not new code. The versions I'm running are:

Mac OS X El Capitan 10.11.6 (15G22010)

XCode Version 8.0 (8A218a)

SageMath version 8.3, Release Date: 2018-08-03

GNU Emacs 27.0.50 (build 1, x86_64-apple-darwin15.6.0, NS appkit-1404.47 Version 10.11.6 (Build 15G22010))

ob-sagemath 0.4

sage-shell-mode 0.3

Have you updated your OS, your version of Xcode, anything like that? Maybe those could interfere with an existing Sage installation.

No, other than normal secutiry updates I've not upgraded XCcode or the OS.

The problem was traced to a misspelling, "sagemth" instead of "sagemath" in two places in ob-sagemath.el file. The best way to solve this problem is to re-install ob-sagemath package in Emacs from melpa repository instead of melpa-stable repository. Don't know when the corrected version will propogate to melpa-stable. Both versions are marked 0.4, so normal package update can't tell which repository has the most recent version.
