The previous change added an assertion that is catching yet another bug in count_events_callback/select_event_lwp_callback: (gdb) PASS: gdb.mi/mi-nonstop.exp: interrupted mi_expect_interrupt: expecting: \*stopped,(reason="signal-received",signal-name="0",signal-meaning="Signal 0"|reason="signal-received",signal-name="SIGINT",signal-meaning="Interrupt")[^ ]* /home/pedro/gdb/mygit/src/gdb/gdbserver/linux-low.c:2329: A problem internal to GDBserver has been detected. select_event_lwp: Assertion `num_events > 0' failed. =thread-group-exited,id="i1" Certainly select_event_lwp_callback should always at least find one event, as it's only called because an event triggered (though we may have more than one: the point of the function is randomly picking one). An LWP that GDB previously asked to continue/step (thus is resumed) and gets a vCont;t request ends up with last_resume_kind == resume_stop. These functions in gdbserver used to filter out events that weren't going to be reported to GDB; I think the last_resume_kind kind check used to make sense at that point, but it no longer does. gdb/gdbserver/ChangeLog: 2015-03-19 Pedro Alves <palves@redhat.com> * linux-low.c (count_events_callback, select_event_lwp_callback): No longer check whether the thread has resume_stop as last resume kind. |

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.
