Comment(by tvb377@…):

 Some tests with gcc45+gdb72:
 With a helloworld-like test
 {{{
 #include <iostream>
 #include <string>

 int     main(int argc, char ** argv)
 {
         std::cout << "Wie gehts denn so?" << std::endl;
         std::string     bla = "Ganz gut!";
         std::cout << bla << std::endl;
         return 0;
 }
 }}}

 I notice:

 {{{
 b main
 r
 -->Program received signal SIGSEGV, Segmentation fault.
 0x0000000100045d73 in std::basic_ostream<char, std::char_traits<char>
 >::sentry::sentry(std::basic_ostream<char, std::char_traits<char> >&)
     () from /opt/local/lib/gcc45/libstdc++.6.dylib
 }}}

 There can be more failures produced like

 {{{
 b 7
 r

 Breakpoint 1, main (argc=1, argv=0x1000002d8) at tst.cpp:7
 7               std::string     bla = "Ganz gut!";
 (gdb) n
 0x00007fff5fc0d500 in ?? ()
 (gdb) n
 Cannot find bounds of current function
 }}}

 or with a different program I also get
 {{{
 Breakpoint 3, main (argc=Could not find the frame base for "main(int,
 char**)".
 }}}
