How to set breakpoint using GDB for x86 assembly when no symbol information is present?
<p>How do I set a breakpoint using GDB for x86 assembly code, when there is no symbol information, i.e. it is not possible to write <code>b *_start</code>.</p>

<p>I'd like to stop execution immediately, but writing <code>b *0</code> isn't very useful, because this would stop execution at address <code>0</code>, but I need to break execution at address <code>x</code> relative to the starting point (which is unknown when no symbol information is present).</p>
