Hi,

While debugging a cpp demo (containing the std::cout call) when I issue 
"p std::cout", I get following warning: "warning: RTTI symbol not found 
for class 'std::ostream'".

Even after setting the print object off.

set print object off
p std::cout
$4 = warning: RTTI symbol not found for class 'std::ostream'


Attached patch is a work around for it.

I also came across following mail thread:
http://www.sourceware.org/ml/gdb-patches/2011-08/msg00474.html

I have verified that this work around also works for the bug 1266 
mentioned in the mail:

b calltest(std::basic_string<char, std::char_traits<char>, 
std::allocator<char> >)
Breakpoint 11 at 0x1d58: file ../src/cpp_.cpp, line 5.
b calltest(foo)
Note: breakpoint 11 also set at pc 0x1d58.
Breakpoint 12 at 0x1d58: file ../src/cpp_.cpp, line 5.
b calltest(std::string)
Note: breakpoints 11 and 12 also set at pc 0x1d58.
Breakpoint 13 at 0x1d58: file ../src/cpp_.cpp, line 5.

Do we have any fix for this issue if not then is it ok to have this work 
around until we get a proper fix?

I have not added the DMGL_VERBOSE to dwarf2_physname and 
lookup_symbol_in_language as I saw the Keith's mail thread after testing 
my patch. Also as I have not seen that part of the code (I thought to 
share the patch before doing so) so I am not sure why its going to be 
useful to have DMGL_VERBOSE added there.

Thanks,
-Ali
