I can certainly sympathize.

FWIW, I too have noticed Emacs 25.2 being quite unstable. For the longest
time, Emacs 24 would run for months without crashing even once. Now it crashes
pretty regularly 2-4 times a day. I wonder now if I'm hitting a memory ceiling
that is triggering the behavior we're describing...

I'm OK with backporting, btw, and would be happy to test if it fixes my issues
too.
