For no good reason the function tui_free_window() is freeing the locator window when we pass it an SRC_WIN or a DISASSEM_WIN. This behavior doesn't make much sense because the locator window is always visible and its contents do not change when the main window changes. This behavior triggers the above PR because when we switch from one TUI window to another (in the PR, from the src window to the asm window) we call tui_free_window() on the previously active window (in the PR, the src window). The function then frees the src window along with the locator window and later we segfault when the now-active asm window tries to query the locator window about the inferior's PC. This patch fixes this apparently wrong behavior by changing tui_free_window() to not free the locator window when we pass it an SRC_WIN or a DISASSEM_WIN. gdb/ChangeLog: PR gdb/18155 * tui/tui-data.c (tui_free_window): Don't free the locator window when passed an SRC_WIN or a DISASSEM_WIN. |

README
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.
