Commit 8971d2788e7 ("gdb: link so_list using intrusive_list") introduced a bug in clear_solib. Instead of passing an `so_list *` to remove_target_sections, it passed an `so_list **`. This was not caught by the compiler, because remove_target_sections takes a `void *` as the "owner", so you can pass it any pointer and it won't complain. This happened because I previously had a patch to change the type of the disposer parameter to be a reference rather than a pointer, so had to change `so` to `&so`. When dropping that patch, I forgot to revert this bit and / or it got re-introduced when handling subsequent merge conflicts. And I didn't properly retest. Fix that, but try to make things less error prone. Add a union to represent the possible owner kinds for a target_section. Trying to pass a pointer to another type than those will not compile.

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.
