I see no branch/jump before the nop, so I take it the breakpoint would be hit
at least once, when stepping into the function.  I still don't understand what
you mean is different, as you haven't really pasted gdb session logs.

I'm sure there's a "stop", "pause", "interrupt" or similarly named
button/action somewhere in your IDE.  It'd be a severely crippled IDE if it
didn't have such a basic feature.
