Hi Latest Vim-7.3b BETA (2401:f380d5227fad) accesses uninitialized memory when doing this:
1) In a terminal, start vim with: $ vim -u NONE /tmp/foo (this creates a swap file /tmp/.foo.swp) 2) In another terminal, start vim with: $ valgrind vim -u NONE /tmp/foo 2> /tmp/vg.log 3) Vim asks... Swap file "/tmp/.foo.swp" already exists! [O]pen Read-Only, (E)dit anyway, (R)ecover, (Q)uit, (A)bort: Type R to recover 4) Observe in /tmp/vg.log the following error: ==7569== Conditional jump or move depends on uninitialised value(s) ==7569== at 0x81347CF: free_string_option (option.c:5316) ==7569== by 0x8110BC7: set_crypt_method (misc2.c:3785) ==7569== by 0x80F5DA3: ml_recover (memline.c:1259) ==7569== by 0x805BBA1: handle_swap_exists (buffer.c:789) ==7569== by 0x80E7F30: create_windows (main.c:2615) ==7569== by 0x80E8E63: main (main.c:808) ==7569== ==7569== Conditional jump or move depends on uninitialised value(s) ==7569== at 0x810FB5B: vim_free (misc2.c:1694) ==7569== by 0x8110BC7: set_crypt_method (misc2.c:3785) ==7569== by 0x80F5DA3: ml_recover (memline.c:1259) ==7569== by 0x805BBA1: handle_swap_exists (buffer.c:789) ==7569== by 0x80E7F30: create_windows (main.c:2615) ==7569== by 0x80E8E63: main (main.c:808) There is also a memory leak: ==14358== 9 bytes in 1 blocks are definitely lost in loss record 21 of 117 ==14358== at 0x4024F70: malloc (vg_replace_malloc.c:236) ==14358== by 0x8110B37: lalloc (misc2.c:919) ==14358== by 0x8110DE8: alloc (misc2.c:818) ==14358== by 0x81114F4: vim_strsave (misc2.c:1236) ==14358== by 0x81115B0: set_crypt_method (misc2.c:3786) ==14358== by 0x80F6423: ml_recover (memline.c:1259) ==14358== by 0x805BC61: handle_swap_exists (buffer.c:789) ==14358== by 0x80E8560: create_windows (main.c:2615) ==14358== by 0x80E9493: main (main.c:808) Vim-7.2.446 is not affected. I did a bisection and I see that bug started to appear in in this changeset: changeset: 2359:d8e4b27cef80 branch: vim73 user: Bram Moolenaar <[email protected]> date: Tue Jul 20 17:32:38 2010 +0200 summary: Change 'cryptmethod' from a number to a string option. Make it glo bal-local. Attached patch fixes it. -- Dominique -- You received this message from the "vim_dev" maillist. Do not top-post! Type your reply below the text you are replying to.
