   As noted from Issue #414, it appears that compilers are optimizing out the clearing of sensitive memory.
   There are a few ways to work around these shortcomings, discussed in CWE-14 and MSC06-C.

   Options include:

   • Casting to volatile during assignment
   • Rolling your own memset_s or using C11’s version
   • Temporarily disabling optimization using #pragma (probably not portable)

   I think this is a duplicate of #185.
