An x32 gdb always issues this warning: (gdb) start Temporary breakpoint 1 at 0x4043e9: file foo.c, line 25. Starting program: a.out warning: linux_ptrace_test_ret_to_nx: Cannot PTRACE_PEEKUSER: Input/output error Temporary breakpoint 1, main (argc=1, argv=0xffffd544) at foo.c:25 25 { (gdb) As described in Linux commit 55283e253771 (x32: Add ptrace for x32): [...] PTRACE_PEEKUSR and PTRACE_POKEUSR are only allowed to access segment and debug registers. [...] The fix is to use PTRACE_GETREGS instead. gdb/ChangeLog: 2016-07-26 Pedro Alves <palves@redhat.com> * nat/linux-ptrace.c: Include "gregset.h". (linux_ptrace_test_ret_to_nx): Use PTRACE_GETREGS instead of PTRACE_PEEKUSER. |
