Re: Error E363 (maxmempattern exceeded) in function 13_Highlight_Matching_Pair

Hello,

I traced this error down to matchparen.vim plugin:

Error detected while processing function <SNR>13_Highlight_Matching_Pair:

line   59:
E363: pattern uses more memory than 'maxmempattern'
Press ENTER or type command to continue

It's impossible to use vim as this error interrupts me all the time when getting around the file.
It happens when loading a relatively small (198kB) text file containing port load dump from opensm (attached). I suspect the problem comes from the contents - the file contains mostly (about 97% lines) of text like this:

 [1] => IN 1106 OUT 1116
 [2] => IN 1106 OUT 1098
 [3] => IN 1106 OUT 1116
 [4] => IN 1106 OUT 1098
 [5] => IN 1106 OUT 1080
[snip]

 

Interestingly, I get the error also when starting vim with --noplugin, bun only once, and if my .vimrc contains colorscheme.
If I comment it out, the error goes away (still with --noplugin).

Without --noplugin, it doesn't matter if colorscheme is used or not.

BUT, with --noplugin, colorcheme left out of .vimrc, then added with ':colorscheme chocolateliquor' once inside vim, I get no error !?? If I source /usr/share/vim/vim73/plugin/matchparen.vim, I get it again.
This is getting quite confusing.

So I disabled colorscheme and removed /usr/share/vim/vim73/plugin/matchparen.vim. Both seem necessary to get rid of the error...

I have tried other schemes (adrian, camo, ...) with the same results.

Thanks for any tips how to proceed.

     My guess is that the --noplugin/colorscheme behavior is a red herring.  If you are getting the same error message, then matchparen.vim is getting :source'd somewhere.  (You can confirm with :scriptnames).  Remember, a colorscheme file (or a syntax file ...) can contain any vim command, including :source and :runtime.

     I am pretty sure that the problem is caused by all the unmatched ">" characters.  If you try

:verbose set mps?

does it include "<:>"?

     Hm, I cannot reproduce the problem while editing your file.  Maybe we have both misdiagnosed the problem ...
