From 010ece9c47f1ac08c9436b133a74472713dd709b Mon Sep 17 00:00:00 2001 From: Luis Machado Date: Mon, 24 Oct 2016 17:44:56 -0500 Subject: [PATCH] Fix obvious gotcha in string comparison This patch fixes a gotcha when comparing exception's messages in exception_print_same. It should've used the statically-allocated string versions msg1 and msg2 instead. As is, it could lead to crashes. gdb/ChangeLog: 2016-10-24 Luis Machado * exec.c (exception_print_same): Fix string comparison to use statically-allocated ones. --- gdb/ChangeLog | 5 +++++ gdb/exec.c | 2 +- 2 files changed, 6 insertions(+), 1 deletion(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index be72369adb..388cc1ff61 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2016-10-24 Luis Machado + + * exec.c (exception_print_same): Fix string comparison to use + statically-allocated ones. + 2016-10-21 Tom Tromey * dwarf2expr.h (class dwarf_expr_context) diff --git a/gdb/exec.c b/gdb/exec.c index d858e996a8..67ecc63630 100644 --- a/gdb/exec.c +++ b/gdb/exec.c @@ -152,7 +152,7 @@ exception_print_same (struct gdb_exception e1, struct gdb_exception e2) return (e1.reason == e2.reason && e1.error == e2.error - && strcmp (e1.message, e2.message) == 0); + && strcmp (msg1, msg2) == 0); } /* See gdbcore.h. */ -- 2.34.1
