Thanks for checking. Closing the bug report.

Not that I know of. I don't know what's holding things up. For some time I've 
thought that users are suffering significantly more by not having the new 
release than they would suffer by getting it "prematurely".

Hello,

I am running emacs 25.1 on a fully updated Fedora 25 linux.

I have stumbled upon the bug when editing the attached file and I can not figure out the issues.

In the above file, if I go to before "Usage..." and start typing anything, including whitespace, emacs crashes. Here is gdb output with bt full and backtrace.

Note that I have no command for xbacktrace.
(gdb) xbacktrace
Undefined command: "xbacktrace".  Try "help".

This has really been a major block for me. So, I was wondering if anyone can help track down the error.

Please feel free to ask questions if something is not clear.

Thanks again! 

Best wishes,
Ranjan
