[Message part 3 (text/plain, inline)]

My emacs 25.1 is crashing these days every 3 hours, irrelevant if Im
on my laptop or work computer, and if Im programming in C or
Clojure. Im always using Fedora, and I install emacs either by
compiling from sources or installed from dnf. Just a paste of my last
gdb crash backtrace: https://www.refheap.com/124399

Crashes are on my computer more likely when saveing or simply using the
cursor around a document. I have aggressive indent mode enabled, haven't
ruled that out yet. Looks to me still that something is not right in
intervals.c?

Thanks for all feedback, hope I don't have to downgrade my emacs.

Best,
Hlödver

Thanks for testing, I'm therefore closing this bug.
