Hi I can reproduce a vim bug filed in Ubuntu launchpad using the latest vim-7.1 (Patches 1-166). Here is a link to the original bug description:
https://bugs.launchpad.net/ubuntu/+source/vim/+bug/68960 Here is how I can reproduce it. I did not use '-u NONE', because standard plugins need to be loaded to reproduce that bug. ".vimrc" file only needs to contain "syntax on" to reproduce it: $ cat ~/.vimrc syntax on $ vim +89 vim_testcase # file "vim_testcase" is attached ... then, when moving cursor around closing parentheses at line 89, observe that vim freezes and takes 100% of CPU (it can be interrupted with Ctrl-C). Trying to debug, I found that vim loops forever in a while(...) loop in syntax.c in function syntax_start(): syntax.c: 562 while (current_lnum < lnum) 563 { ... ... 596 load_current_state(prev); ... ... 609 line_breakcheck(); 610 if (got_int) 611 { 612 current_lnum = lnum; 613 break; 614 } 615 } This while loop never ends with attached "vim_testcase" file. Adding some printf(), I can see that: - Before entering above while loop: - current_lnum == 65 - lnum == 80 - Then when iterating in the while loop: - lnum remains unchanged (80) - current_lnum becomes: 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, etc. current_lnum never reaches lnum (80) so loop never ends. current_lnum goes back from 78 to 65 when calling load_current_state(prev) at line 596. I do not understand the idea behind load_current_state() and store_current_state() to go beyond and come up with fix for this. I'm using vim-7.1 (Patches 1-166) on Linux x86, built with 'configure --with-features=huge'. -- Dominique --~--~---------~--~----~------------~-------~--~----~ You received this message from the "vim_dev" maillist.
