[sage-release] Re: Sage 8.9.beta9 released

2019-09-03 Thread John H Palmieri
With a Python 3 build on OS X, I get a sporadic failure in 
numerical/linear_tensor_element.pyx — it fails not every time, but at least 
half the time. As far as I can tell, this is due to #27587 (that is, I get 
failures with 8.9.beta8 + that ticket, but not with 8.9.beta8), but I don't 
understand why.

$ ./sage -t src/sage/numerical/linear_tensor_element.pyx

This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.
