-fsanitize=address pointed out a use-after-free in gdbserver. In particular, handle_detach could reference "process" after it was deleted by detach_inferior. Avoiding this also necessitated changing target_ops::join to take a pid rather than a process_info*. Tested by the buildbot using a few of the gdbserver builders. gdb/gdbserver/ChangeLog 2018-11-29 Tom Tromey <tom@tromey.com> * win32-low.c (win32_join): Take pid, not process. * target.h (struct target_ops) <join>: Change argument type. (join_inferior): Change argument name. * spu-low.c (spu_join): Take pid, not process. * server.c (handle_detach): Preserve pid before destroying process. * lynx-low.c (lynx_join): Take pid, not process. * linux-low.c (linux_join): Take pid, not process.
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; if with a libg++ release, see libg++/README, etc. 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.
