No, there are usually two possible causes of this problem, both of them 
are not in the kernel:

If you try building the module again and the error does _not_ show up 
at _exactly_ the same place you have a hardware problem (e.g. bad RAM).

If the problem does reproducible show up at the same place, it's a bug 
in gcc. In this case, gcc has already told you where to report it (but I 
don't know whether RedHat 7.3 is still supported by RedHat).
