I am using debian squeeze.
2.6.32-5-vserver-amd64 #1 SMP Sat Jul 24 03:17:33 UTC 2010 x86_64 GNU/Linux
It seems my gdb is configured for i686 and not x64.
I can't create any executables with g++ that gdb is able to debug.
$ file a.out
a.out: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, not stripped
$ gdb a.out

I googled and found this:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=425838
It looks like a binutils incompatibility came up back in 2007 with lenny. Is it something similar?
