There is the following statement in gdb.texinfo:

  Currently, @value{GDBN} works best when debugging C@t{++} code that
  is compiled with @value{NGCC} 2.95.3 or with @value{NGCC} 3.1 or
  newer, using the options @option{-gdwarf-2} or @option{-gstabs+}.
  DWARF 2 is preferred over stabs+.  Most configurations of
  @value{NGCC} emit either DWARF 2 or stabs+ as their default debug
  format, so you usually don't need to specify a debug format
  explicitly.  Other compilers and/or debug formats are likely to work
  badly or not at all when using @value{GDBN} to debug C@t{++} code.

But it probably should be mentioned more prominently somewhere.  I'm
not sure exactly what we want to say: we're not going through and
ripping out support for HP's C++ compiler, after all.  (At least not
yet...)
