Hi,
In older versions of gdb (at least until 7.11 which i'm using and
possibly later) I see the following behavior when starting gdb and
typing, 'b main'
"\r\n\032\032post-prompt\r\n"
"Breakpoint 1 at 0x4006c0: file test.cpp, line 42.\r\n"
"\r\n\032\032breakpoints-invalid\r\n"
In GDB 9.1, I'm see the following,
"\r\n\032\032post-prompt\r\n"
"\r\nBreakpoint 1 at \033[34m0x4006c0\033[m: file \033[32mtest.cpp\033[m, line 42."
"\r\n\032\032breakpoints-invalid\r\n"
You can see that the newline moved on the "Breakpoint 1" line
from the end of the line (in older versions) to the beginning of the
line (in newer versions).
This ultimately caused CGDB to misbehave.
Correctly working CGDB,
Reading symbols from ./main...done.
(gdb) b main
Breakpoint 1 at 0x4006c0: file test.cpp, line 42.
(gdb)

(gdb) b main
Breakpoint 1 at 0x4006c0: file test.cpp, line 42.(gdb)
Was this change to the annotations made on purpose?
Thanks,
Bob Rossi

I haven't followed development much, lately ( :-( ), but I don't
think so. This looks similer to:
https://sourceware.org/bugzilla/show_bug.cgi?id=25190
That particular PR is reported as being fixed for 9.1, so it's
not the same problem, or the fix was incomplete.
Have you tried master, by any chance?

Thanks for pointing to the bug report.

Not yet. I might have to.
However, I was playing around and found out that when
set height 0
is used, gdb shows the bug. However if,
set pagination off
is used, the error is gone.
I found that really strange as the documentation seems
to indicate that 'set height 0' and 'set pagination off'
are equivalent. I guess not!
I may change CGDB to set pagination off to work around
this issue. Is there anything else I should do at this point?
Thanks,
Bob Rossi
