The call to bfd_check_format in try_open_dwop_file:
...
/* The operations below are not thread-safe, use a lock to synchronize
concurrent accesses. */
static gdb::mutex mutex;
gdb::lock_guard<gdb::mutex> lock (mutex);
if (!bfd_check_format (sym_bfd.get (), bfd_object))
return NULL;
...
accesses the sym_bfd.get () BFD, so it should be guarded by the global BFD
lock.
Fix this by:
- using the global BFD lock in gdb_bfd_check_format, and
- removing the local lock.
Likewise, use the global BFD lock in gdb_bfd_check_format_matches.
The local lock also guarded a call to gdb_bfd_record_inclusion, which doesn't
do any locking, so likewise use the global BFD lock in
gdb_bfd_record_inclusion.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README, and so on. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
