Hello !
I can reproduce it with your provided syntax file and my debian vim
7.2.330. I haven't looked into the syntax file in detail, but it seems
to be the problem. Using your syntax php file and layout.php that you
provided[1], this simple_vimrc script shows the problem:
,----
| profile start my_profile_php
| fun Profile()
| syntax on
| e layer.php
| set fdm=syntax
| "call feedkeys(":set synmaxcol=100\n", 't')
| call feedkeys(":8d\n",'t')
| call feedkeys("u",'t')
| call feedkeys("zo",'t')
| call feedkeys("dw",'t')
| call feedkeys(":q!\n",'t')
| endfun
|
| profile func Profile
|
| call Profile()
`----
(Notice, that first deleting the whole fold starting at line 8 and then
undoing the deletion will make vim unresponsive for several minutes:
c...@t41:~$ time vim -u simple_vimrc -U NONE -N
"layer.php" "layer.php" 1595L, 39500C
Press ENTER or type command to continue
real 3m4.249s
user 2m58.199s
sys 0m1.460s
c...@t41:~$
Profiling did not resolve anything special:

If you comment out the lines 8 and 7 it works ok:
c...@t41:~$ cat simple_vimrc&& time vim -u simple_vimrc -U NONE -N
profile start my_profile_php3
fun Profile()
syntax on
e layer.php
set fdm=syntax
"call feedkeys(":set synmaxcol=100\n", 't')
"call feedkeys(":8d\n",'t')
"call feedkeys("u",'t')
call feedkeys("zo",'t')
call feedkeys("dw",'t')
call feedkeys(":q!\n",'t')
endfun
profile func Profile
call Profile()
"layer.php" "layer.php" 1595L, 39500C
Press ENTER or type command to continue
real 0m1.024s
user 0m0.900s
sys 0m0.048s
One thing that helps a little is to set synmaxcol to a much lower value:
c...@t41:~$ cat simple_vimrc&& time vim -u simple_vimrc -U NONE -N
profile start my_profile_php4
fun Profile()
syntax on
e layer.php
set fdm=syntax
call feedkeys(":set synmaxcol=100\n", 't')
call feedkeys(":8d\n",'t')
call feedkeys("u",'t')
call feedkeys("zo",'t')
call feedkeys("dw",'t')
call feedkeys(":q!\n",'t')
endfun
profile func Profile
call Profile()
"layer.php" "layer.php" 1595L, 39500C
Press ENTER or type command to continue
real 0m23.974s
user 0m23.293s
sys 0m0.216s
BTW: using the debian provided syntax files, does not show the problem:
c...@t41:~$ cat simple_vimrc&& time vim -u simple_vimrc -U NONE -N
let php_folding=1
profile start my_profile_php6
fun Profile()
syntax on
e layer.php
set fdm=syntax
"call feedkeys(":set synmaxcol=100\n", 't')
call feedkeys(":8d\n",'t')
call feedkeys("u",'t')
call feedkeys("zo",'t')
call feedkeys("dw",'t')
call feedkeys(":q!\n",'t')
endfun
profile func Profile
call Profile()
"layer.php" "layer.php" 1595L, 39500C
Press ENTER or type command to continue
real 0m3.506s
user 0m3.292s
sys 0m0.096s
[1] To make sure, I run this test as a separate user with a new ~/.vim
directory that contains only these files:
c...@t41:~$ find .vim/
.vim/
.vim/syntax
.vim/syntax/php.vim
:scriptnames does show, that some standard plugins are loaded:
1: /home/cb/simple_vimrc
2: /usr/share/vim/vim72/syntax/syntax.vim
3: /usr/share/vim/vim72/syntax/synload.vim
4: /usr/share/vim/vim72/syntax/syncolor.vim

17: /usr/share/vim/vim72/plugin/zipPlugin.vim
Thanks for your help, Christian !
But i don't know where is the problem in my syntax file...
I have no problem with it before patch 274.
And i have no problem with default php syntax file after patch 274, but
my custom file is very different, so default syntax file is not relevant
to find the problem in my custom syntax file :/.
Best regards,
Fred.
