Running gdb.threads/process-dies-while-handling-bp.exp against gdbserver sometimes FAILs because GDBserver drops the connection, but the logs leave no clue on what the reason could be. Running manually a few times, I saw the same: $ ./gdbserver/gdbserver --multi :9999 testsuite/gdb.threads/process-dies-while-handling-bp Process testsuite/gdb.threads/process-dies-while-handling-bp created; pid = 12766 Listening on port 9999 Remote debugging from host 127.0.0.1 Listening on port 9999 Child exited with status 0 Child exited with status 0 What happened is that an exception escaped and gdbserver reopened the connection, which led to that second "Listening on port 9999" output. The error was a failure to access registers from a now-dead thread. The exception probably shouldn't have escaped here, but meanwhile, this at least makes the issue less mysterious. Tested on x86_64 Fedora 20. gdb/gdbserver/ChangeLog: 2015-08-06 Pedro Alves <palves@redhat.com> * server.c (captured_main): On error, print the exception message to stderr, and if run_once is set, throw a quit. |

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.
