gdba locals buffer does not show function arguments

[Tom Tromey]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I was debugging using gdba today and found that the "locals" buffer
does not show the arguments to the current function.

I expected it to show both the local variables and the function
arguments.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/22.0.990/etc/DEBUG for instructions.
