From: Jan Vrany Date: Thu, 30 May 2019 12:04:26 +0000 (+0100) Subject: Initialize variable word in complete X-Git-Tag: binutils-2_33~1032 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0ef209f22c24b9243de68c35c576f7111198f915;p=external%2Fbinutils.git Initialize variable word in complete The complete function should set parameter word to the end of the word to complete. However, completion_find_completion_word may fail, leaving word uninitialized. To make sure word is always set, initialize it to the completion point which is the end of the line parameter. gdb/Changelog PR cli/24587 * completer.c (complete): Initialize variable word. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 2ab3615..a32c606 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2019-05-30 Jan Vrany + + PR cli/24587 + * completer.c (complete): Initialize variable word. + 2019-05-29 Sergio Durigan Junior Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1708192 diff --git a/gdb/completer.c b/gdb/completer.c index cc2f80b..24c8446 100644 --- a/gdb/completer.c +++ b/gdb/completer.c @@ -1622,6 +1622,13 @@ complete (const char *line, char const **word, int *quote_char) completion_tracker tracker_handle_completions; completion_tracker *tracker; + /* The WORD should be set to the end of word to complete.
