Well, I can see the build command on the webpage there, and assuming this is the same gcc we all know and love without any cleverness going on, it&#x27;s not a debug build of any kind as far as I can see:<p><pre><code>    gcc segfault.c
</code></pre>
Now that I think about it, I&#x27;m not aware that gcc C compiler even offers the option to deliberately zero initialise non-static local variables, so unless I&#x27;ve missed a switch somewhere there is no arrangement of options available for a &quot;debug build&quot; to do this. I recall the GCC Fortran compiler did offer it.
