Hi,

a038fa3e14a477d4d72a26c2e139fa47d2774be2 is the first bad commit
commit a038fa3e14a477d4d72a26c2e139fa47d2774be2
Author: Markus Metzger <markus.t.metzger@intel.com>
    stack: check frame_unwind_caller_id
[PATCH v3 2/3] stack: check frame_unwind_caller_id
https://sourceware.org/ml/gdb-patches/2016-02/msg00363.html
Message-Id: <1455207283-12660-2-git-send-email-markus.t.metzger@intel.com>

 (gdb) PASS: gdb.dwarf2/dw2-undefined-ret-addr.exp: up refuses to go up

-(gdb) PASS: gdb.dwarf2/dw2-undefined-ret-addr.exp: info frame
+(gdb) FAIL: gdb.dwarf2/dw2-undefined-ret-addr.exp: info frame

It happens on normal native Fedora 23 x86_64.

I am not completely sure about the reasons but it looks to me GDB behavior has
just changed.

OK for check-in?


Thanks,
Jan
