The following behaviour was observed in GDB:
(gdb) show remote X-packet
Support for the `p' packet is auto-detected, currently unknown.
Note the message mentions the 'p' packet. This is a regression since
this commit:
commit 8579fd136a614985bd27f20539c7bb7c5a51287d

gdb/gdbsupport: make xstrprintf and xstrvprintf return a unique_ptr
Before this commit the behaviour was:
(gdb) show remote X-packet
Support for the `X' packet is auto-detected, currently unknown.
The problem was caused by a failed attempt to ensure that some
allocated strings were deleted when GDB exits. The code in the above
commit attempted to make use of 'static' to solve this problem,
however, the solution was just wrong.
In this new commit I instead allocate a static vector into which all
the allocated strings are stored, this ensures the strings are
released when GDB exits (which makes output from tools like valgrind
cleaner), but each string within the vector can be unique, which fixes
the regression.
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.
