From 0e1a6a5169023ee0c19de2c9160b469e43634b21 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Mon, 25 Jul 2016 12:42:18 +0100 Subject: [PATCH] linux-procfs: Handle lowercase "t (tracing stop)" state Since Linux 2.6.33, /proc/PID/status shows "t (tracing stop)", with lowercase 't'. Because GDB is only expecting "T (tracing stop)", GDB can incorrectly suppress errors in check_ptrace_stopped_lwp_gone: 1578 if (!check_ptrace_stopped_lwp_gone (lp)) 1579 throw_exception (ex); Ref: https://sourceware.org/ml/gdb-patches/2016-06/msg00072.html 2016-07-25 Pedro Alves Jan Kratochvil * nat/linux-procfs.c (parse_proc_status_state): Handle lowercase 't'. --- gdb/ChangeLog | 6 ++++++ gdb/nat/linux-procfs.c | 3 +++ 2 files changed, 9 insertions(+) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 0840a69..c346a90 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,4 +1,10 @@ 2016-07-25 Pedro Alves + Jan Kratochvil + + * nat/linux-procfs.c (parse_proc_status_state): Handle lowercase + 't'. + +2016-07-25 Pedro Alves * nat/linux-procfs.c (enum proc_state): New enum.
