Dear all,

I have some problems building the mvapich 2.3.5 on a laptop with Fedora 33/x86_64.
The common error message is:

  error: size of array element is not a multiple of its alignment

Below I paste some information and I also attach some relevant files. 
Please, some clue to solve it. 

Thanks in advance.

Regards 
Jorge.
