Subject: gdb, remote: fix notify debug nullptr dereference
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cd52261cfb4d146b30e3a0ce456a582980f5b11b;p=thirdparty%2Fbinutils-gdb.git

gdb, remote: fix notify debug nullptr dereference

In remote_target:push_stop_reply, notif debug prints an element that has
been moved.  Print the element at the destination, instead.
