See http://sourceware.org/ml/gdb/2010-07/msg00118.html for a description of the problem. Namely, the file and fullname fields are inverted in the output of the -file-list-exec-source-files GDB/MI command: (gdb) interpreter-exec mi -file-list-exec-source-files ^done,files=[{file="/takamaka.a/brobecke/ex/list-exec-source-files/foo.c",fullname="foo.c"},{file="/takamaka.a/brobecke/ex/list-exec-source-files/foo.c",fullname="foo.c"},{file="",fullname="init.c"},{file="",fullname="../sysdeps/x86_64/elf/start.S"},{file="",fullname="../sysdeps/x86_64/elf/start.S"}] It turns out to be a silly thinko: The map_symbol_filenames function calls the psymtab version of map_symbol_filenames routine, and this version called the callback function with filename and fullname in the wrong order (fullname/filename instead of filename/fullname). The routine description in symfile.h confirst that expected order for the FUN callback parameters: /* Call a callback for every file defined in OBJFILE. FUN is the callback. It is passed the file's name, the file's full name, and the DATA passed to this function. */ void (*map_symbol_filenames) (struct objfile *objfile, void (*fun) (const char *, const char *, void *), void *data); Fixing this error uncovered another location where the arguments were reversed: maybe_add_partial_symtab_filename. Once the first error was fixed, the debugger would crash while attempting to do completion, because it was given a NULL fullname instead of the non-NULL filename. gdb/ChangeLog: * psymtab.c (map_symbol_filenames_psymtab): Call FUN with the arguments in the correct order. * symtab.c (maybe_add_partial_symtab_filename): Declare the arguments in the correct order.

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.
