I see the crash with gdb (5.1.90CVS-3) but with gdb 2003-07-04-cvs, I get the output:
{<basic_iostream<char,std::char_traits<char> >> = {<basic_istream<
char,std::char_traits<char> >> = {<basic_ios<char,std::char_traits<char> >> = <invalid

      _vptr.basic_istream = 0x10, _M_gcount = 139083320}, <basic_ostream<

  _M_stringbuf = {<basic_streambuf<char,std::char_traits<char> >> =

      _M_dataplus = {<allocator<char>> = {<No data fields>}, _M_p = 0x11 <Address 0x11 
out of bounds>}}}}

This is with the mainline gcc (20030705).
I will attach the output of readelf.
Can you look at the output and tell me if this bug still exists?

What's the debugging output you put in the bug log from?  There's no
basic_iostream in this testcase at all.  From the readelf output, the
bug is still there.

I had forgot to copy and paste the "$1 = " in front of output (see the '{').
I see how you got confused.  
I also see how to detect the problem now in the "readelf --debug-dump" output.
It still exists on the mainline (20030724).

--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
With gcc 7.5 and gcc 13.2 I see

(gdb) p/r s
$3 = <incomplete type>
(gdb) ptype s
type = std::stringstream

and the python pretty-printers "ICE" like

(gdb) p s
Python Exception <class 'IndexError'>: list index out of range

The DW_TAG_typedef is still as reported, to a DW_AT_declaration, and the
variable DIE only refers to the typedef DIE.

So - reconfirmed.  Might be also a C++ frontend representation issue.

Maybe related to PR 12385.
