From 7243b1cbde8a08deab6bf29b452b3383fa4f6d8d Mon Sep 17 00:00:00 2001 From: zeertzjq Date: Sat, 3 Sep 2022 06:46:30 +0800 Subject: vim-patch:9.0.0360: crash when invalid line number on :for is ignored Problem: Crash when invalid line number on :for is ignored. Solution: Do not check breakpoint for non-existing line. https://github.com/vim/vim/commit/35d21c6830fc2d68aca838424a0e786821c5891c Test does not fail without the fix in Nvim as Nvim uses 0 when line number overflows. If it is changed to MAXLNUM then the test does fail without the fix, but using 0 seems better as E481 is still given. --- src/nvim/ex_docmd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/nvim/ex_docmd.c') diff --git a/src/nvim/ex_docmd.c b/src/nvim/ex_docmd.c index c2c5bb90ce..6517ebd081 100644 --- a/src/nvim/ex_docmd.c +++ b/src/nvim/ex_docmd.c @@ -642,7 +642,7 @@ int do_cmdline(char *cmdline, LineGetter fgetline, void *cookie, int flags) // Check for the next breakpoint at or after the ":while" // or ":for". - if (breakpoint != NULL) { + if (breakpoint != NULL && lines_ga.ga_len > current_line) { *breakpoint = dbg_find_breakpoint(getline_equal(fgetline, cookie, getsourceline), fname, ((wcmd_T *)lines_ga.ga_data)[current_line].lnum - 1); *dbg_tick = debug_tick; -- cgit
