title: 64 bit windows assembler debugging
body: <p>I am trying to debug some assembler code on windows.  For 32 bit code I was using Ollydbg, but it is unable to open 64-bit exe files.</p>
  
  <p>I also tried using the visual studio debugger but I think the stack is somehow getting corrupted and I can't figure out how to place a breakpoint at the program entry, so this doesn't work</p>
  
  <p>So are there any free programs that work?</p>
  
  <p>If it matters I am using nasm and then gcc to compile the exe's</p>
