Raymond Hettinger <[email protected]> added the comment:
A new intermittent problem has arisen on macOS since I updated to Catalina. It
occurs on both 10.15.0 and 10.15.1. I'm using the 3.8.0 mac 64-bit install
taken directly from python.org.
In a long-running session of IDLE, the process freezes-up during File/SaveAs.
The file save dialog comes-up. When typing the filename, the dialog window
greys-out, the list of files goes blank, and the situation is unrecoverable
(see the attached screenshot).
And see below for the core dump in the terminal session.
