You can't really know, in an optimized build.  GCC is very good in
collapsing multiple calls to th same function into a single call.

I suggest to build with -O0, and then trying to crash.  At least then
the backtrace and the line numbers won't lie.  And you get to actually
see the values of the variables as a bonus, instead of all those
<value optimized out> thingies.
