I don't know how to reproduce this issue. Perhaps you have something special in your vimrc or use a plugin that is triggering the bug. If you don't mind sharing your ~/.vimrc and ~/.vim content, or tell us which plugins you use, it could perhaps help others to reproduce it. Valgrind does not exist for Windows there is no plan to port it to Windows. See: http://valgrind.org/info/platforms.html There are as far as I know only "expensive" alternative to Valgrind/memcheck for Windows (purify, insure++, BoundsChecker and others) which can find memory issues on Windows, but but in very different ways than Valgrind. How about settings the pointers to NULL right after freeing them in free_screenlines(...) so if something is using free memory, it will at least crash immediately. It may help to detect problems earlier. Of course the bug may be something else than using freed memory anyway but it's worth trying. You can do as in the patch below (this is just for debugging, we should not need in theory to apply this patch of Vim): diff -r aab202d244b6 src/screen.c --- a/src/screen.c Wed Mar 10 17:16:12 2010 +0100 +++ b/src/screen.c Fri Mar 12 05:26:48 2010 +0100 @@ -7780,17 +7780,19 @@ #ifdef FEAT_MBYTE int i; - vim_free(ScreenLinesUC); + vim_free(ScreenLinesUC); ScreenLinesUC = NULL; for (i = 0; i < Screen_mco; ++i) - vim_free(ScreenLinesC[i]); - vim_free(ScreenLines2); -#endif - vim_free(ScreenLines); - vim_free(ScreenAttrs); - vim_free(LineOffset); - vim_free(LineWraps); -#ifdef FEAT_WINDOWS - vim_free(TabPageIdxs); + { + vim_free(ScreenLinesC[i]); ScreenLinesC[i] = NULL; + } + vim_free(ScreenLines2); ScreenLines2 = NULL; +#endif + vim_free(ScreenLines); ScreenLines = NULL; + vim_free(ScreenAttrs); ScreenAttrs = NULL; + vim_free(LineOffset); LineOffset = NULL; + vim_free(LineWraps); LineWraps = NULL; +#ifdef FEAT_WINDOWS + vim_free(TabPageIdxs); TabPageIdxs = NULL; #endif } You may want to do the same in other places which you may think are relevant. Maybe it's related to asynchronously resizing the window since I see some resize in the stack. So trying to resize the window with the mouse may help to do some stress tests. > Incidently, today is my last day before I head on vacation for a week > (for future followups). > > Thanks, > Dave I hope it does not ruin your vacations! :-) Cheers -- Dominique -- You received this message from the "vim_dev" maillist.
