The problem is that I only placed one breakpoint, how can I have a "breakpoint site 3"? Here's my interaction with lldb:<div><div><br></div><div>➜ tests ±:(master) ! lldb ./a</div><div>Current executable set to './a' (x86_64).</div>
<div>(lldb) breakpoint set -n main</div><div>Breakpoint created: 1: name = 'main', locations = 1</div><div>(lldb) run</div><div>DynamicLoaderMacOSXDYLD::PrivateInitialize() process state = launching</div><div>DynamicLoaderMacOSXDYLD::SetNotificationBreakpoint() process state = launching</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Internal breakpoints have negative IDs, so this hit one of your breakpoints, breakpoint 3.<br>
<br>
Do a:<br>
<br>
(lldb) breakpoint list --full<br>
<br>
And see which breakpoint it is hitting.<br>
