From 43368e1d9ab8437079001f7a5f6ae2241acaece3 Mon Sep 17 00:00:00 2001 From: Markus Metzger Date: Wed, 23 Dec 2015 13:53:53 +0100 Subject: btrace: do not return out of TRY/CATCH In btrace_pt_readmem_callback, we read memory inside TRY/CATCH and return in case of an error return value. This corrupts the cleanup chain, which eventually results in a SEGV when doing or discarding cleanups later on. gdb/ * btrace.c (btrace_pt_readmem_callback): Do not return in TRY/CATCH. testsuite/ * gdb.btrace/dlopen.exp: New. * gdb.btrace/dlopen.c: New. * gdb.btrace/dlopen-dso.c: New. --- gdb/testsuite/gdb.btrace/dlopen-dso.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 gdb/testsuite/gdb.btrace/dlopen-dso.c (limited to 'gdb/testsuite/gdb.btrace/dlopen-dso.c') diff --git a/gdb/testsuite/gdb.btrace/dlopen-dso.c b/gdb/testsuite/gdb.btrace/dlopen-dso.c new file mode 100644 index 0000000..3a1733e --- /dev/null +++ b/gdb/testsuite/gdb.btrace/dlopen-dso.c @@ -0,0 +1,22 @@ +/* This testcase is part of GDB, the GNU debugger. + + Copyright 2015-2016 Free Software Foundation, Inc. + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
