26.1 seems pretty stable or else I haven't used it long enough. No hang
or anything fatal. It's becoming harder (if not impossible) to use gdb
on macOS but I always build emacs with debug info just in case. My
situation is a bit hard to get further because there is no known way to
hang emacs except waiting for the hang to show itself.

Thanks for the efforts in improving Emacs on this area.
