From 59f413d5412217c5c6f9e25d0279a1997426d60a Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Mon, 4 Jun 2018 12:26:39 +0100 Subject: Fix macOS null pointer dereference reports that macOS gdb crashes with a null pointer dereference in push_target(struct target_ops *). This commit fixes that. The problem is that commit f6ac5f3d63e0 ("Convert struct target_ops to C++") left the darwin_ops global uninitialized. We don't need that global anymore, we can use the (new) get_native_target function instead for the same effect. gdb/ChangeLog: 2018-06-04 Pedro Alves * darwin-nat.c (darwin_ops): Delete. (darwin_attach_pid): Use get_native_target. --- gdb/darwin-nat.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'gdb/darwin-nat.c') diff --git a/gdb/darwin-nat.c b/gdb/darwin-nat.c index 0b1a491..ed1ed32 100644 --- a/gdb/darwin-nat.c +++ b/gdb/darwin-nat.c @@ -97,9 +97,6 @@ static void darwin_deallocate_exception_ports (darwin_inferior *inf); static void darwin_setup_exceptions (struct inferior *inf); static void darwin_deallocate_threads (struct inferior *inf); -/* Target operations for Darwin. */ -static struct target_ops *darwin_ops; - /* Task identifier of gdb. */ static task_t gdb_task; @@ -1656,6 +1653,7 @@ darwin_attach_pid (struct inferior *inf) darwin_setup_exceptions (inf); + target_ops *darwin_ops = get_native_target (); if (!target_is_pushed (darwin_ops)) push_target (darwin_ops); } -- cgit v1.1
