This is a perfectly possible case, and half of ctf_bfdopen_ctfsect handled it fine. The other half hit a divide by zero or two before we got that far, and had no code path to load the strtab from anywhere in the absence of a symtab to point at it in any case. So, as a fallback, if there is no symtab, try loading ".strtab" explicitly by name, like we used to before we started looking for the strtab the symtab used. Of course, such a strtab is not kept hold of by BFD, so this means we have to bring back the code to possibly explicitly free the strtab that we read in. libctf/ * ctf-impl.h (struct ctf_archive_internal) <ctfi_free_strsect> New. * ctf-open-bfd.c (ctf_bfdopen_ctfsect): Explicitly open a strtab if the input has no symtab, rather than dividing by zero. Arrange to free it later via ctfi_free_ctfsect. * ctf-archive.c (ctf_new_archive_internal): Do not ctfi_free_strsect by default. (ctf_arc_close): Possibly free it here.
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.
