I see this failure:
(gdb) run ^M

(gdb) FAIL: gdb.dwarf2/dw2-inline-param.exp: runto: run to *0x113b
The test loads the binary in GDB, grabs the address of a symbol, strips
the binary, reloads it in GDB, runs the program, and then tries to place
a breakpoint at that address. The problem is that the binary is built
as position independent, so the address GDB grabs in the first place
isn't where the code ends up after running.
Fix this by linking the binary as non-position-independent. The
alternative would be to compute the relocated address where to place the
breakpoint, but that's not very straightforward, unfortunately.
I was confused for a while, I was trying to load the binary in GDB
manually to get the symbol address, but GDB was telling me the symbol
could not be found. Meanwhile, it clearly worked in gdb.log. The thing
is that GDB strips the binary in-place, so we don't have access to the
intermediary binary with symbols. Change the test to output the
stripped binary to a separate file instead.

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.
