It's a regression.
Disassembly shows only small part of the code (see attached screenshot).

Comment 3 Alexander Pepin 2010-12-07 14:51:47 UTC 
In build 20101207 Disassembly still looks incomplete:
!int main(int argc, char**argv) {
main+0: lea    0x4(%esp),%ecx
main+4: and    $0xfffffff0,%esp
main+7: pushl  -0x4(%ecx)
main+10: push   %ebp
main+11: mov    %esp,%ebp
main+13: push   %ebx
main+14: push   %ecx
main+15: sub    $0x20,%esp
main+18: mov    %ecx,-0x1c(%ebp)
main+21: call   0x401310 <__main>
!    // Prints welcome message...
!    std::cout << "Welcome ..." << std::endl;
main+26: movl   $0x4020a0,0x4(%esp)
main+34: movl   $0x6c4f5a60,(%esp)
_fu0___ZSt4cout+4: call   0x4012a8 <_ZStlsISt11char_traitsIcEERSt13basic_ostreamIcT_ES5_PKc>

!

_fu0___ZSt4cout()

Comment 4 Alexander Pepin 2010-12-07 15:17:25 UTC 
The regression is fixed now. Now it works similarly to NB6.9.1 with the same tool collection. The bug is downgraded to P3.
Comment 5 Egor Ushakov 2010-12-10 13:29:41 UTC 
so what's left to fix here?
Comment 6 Egor Ushakov 2010-12-10 13:34:50 UTC 
we show exactly what gdb provides plus source code in comments
Comment 7 Alexander Pepin 2010-12-10 13:56:52 UTC 
It would be nice to see real disassembly.
