PR compile/29541 points out that some of the C++ tests in gdb.compile will time out when the glibc debuginfo is installed. This was interfering with my hacking on gdb by making test runs extremely long, so I looked into it. Internally the bug seems to be that gdb tries to convert multiple symbols named "var" via the compiler interface; one such symbol (I didn't track it down too far) causes the C++ compiler plugin to crash. Unfortunately, the crash is reported as a timeout, as the gdb side of the plugin simply hangs. This seems like a bug in the plugin RPC mechanism and, worse, apparently when I wrote this stuff I didn't really consider error reporting very much at all, so gdb can't really detect failures in the first place. Anyway... this patch works around the timeout by compiling a simple test that should provoke this bug, and then using "untested" if it notices a GCC crash.

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.
