This is a weird bug.
When the attached test_vim.txt file is opened in Vim, and scrolled
down to line 372, Vim hangs and consumes 24% of CPU.
This only happens with the attached vimrc and test_vim.txt. All other
files I tried work nice with the attached vimrc.
The test_vim.txt file works nice if it is:
* opened in less
* opened in vi
* opened in Vim with the last 7 lines of the attached vimrc commented
The test_vim.txt file also works nice if a blank line is inserted on
line 372 like this:
FILE_CONTENT FILE_CONTENT FILE_CONTENT

The attached test_vim.txt file is 504 lines long.
I have reproduced the bug by copying lines 360 to line 375 into a new
file, but it only hangs for a couple seconds. And does not hang if
the last 7 lines of the vimrc are commented.
I am running Vim version 7.4.6.40 on Linux Fedora 22 on hardware
Haswell Intel NUC Kit D54250WYK.
Thank you.
1) Try to reproduce according to the description here:
http://vimhelp.appspot.com/vim_faq.txt.html#faq-2.5
2) I suspect, markdown syntax highlighting is causing this problem for
you.
(since it goes away, if you disable setting the filetype)
You can check with the :syntime command, which pattern is slow
(see :h :syntime) and also you might want to try to switch to the old
re-engine (:set re=1 see :h two-engines), to see if this makes a
difference.
If this is the case, contact the maintainer of the markdown syntax file.
He can likely assist on how to proceed and hopefully fix the syntax
file.
Best,
Christian
