On openSUSE Tumbleweed I run into:
...
FAIL: gdb.tui/basic.exp: asm window shows main
ERROR: invalid command name "_csi_L"
...
Using a minimal example, we get:
...
$ gdb -q outputs/gdb.tui/basic/basic -ex "tui enable" -ex "layout asm"
<TUI output>
src/gdb/ui-style.c:243: internal-error: bool \
ui_file_style::parse(const char*, size_t*): Assertion `match == 0' failed.
...
The problem is in len_without_escapes, where we detect the start of an escape
sequence, but then pass ptr to style.parse while ptr no longer points to the
escape due to the ptr++ in the while condition:
...
while ((c = *ptr++) != '\0')
{
if (c == '\033')
{
ui_file_style style;
size_t n_read;
if (style.parse (ptr, &n_read))
...
Fix this by removing the ++ in the while condition, and adding ptr++ in the
loop body where appropriate.
Tested on x86_64-linux.

* tui/tui-disasm.c (len_without_escapes): Pass ptr pointing at escape
to style.parse.

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.
