Re: Crashing Vim 7.4a9 snapshot 68 with folding
Update:
As I have written earlier, the crash was introduced with
Vim 7.3.1185.
And here is the RegEx that causes the crash:
syn match pandocPCite /@\%[\w\-]*/
It is part of the citation handling code in ~/.vim/syntax/pandoc.vim
from vim-pandoc.
" Citations:
" parenthetical citations
syn match pandocPCite /\[-\{0,1}@.\{-}\]/
contains=pandocEmphasis,pandocStrong,pandocLatex,@Spell
" syn match pandocPCite /\[\w.\{-}\s-\?.\{-}\]/
contains=pandocEmphasis,pandocStrong
" in-text citations without location
" syn match pandocPCite /@\%[\w\-]*/
" in-text citations with location
syn match pandocPCite /@\w*\s\[.\{-}\]/

I rebuild Vim 7.3.754 with my current compiler and it crashed. Any idea where to look?
