Hi
I did:
   immutable uint  MemSize=100;  // Memory size in bytes.

// Memory Pool
   ubyte[MemSize]  MemPool = 8;

And had a look in memory.
I think the compiler set up 101 '8's, not 100 in memory.

Which I did not expect.

Best regards

When I look there are 100. What makes you think there are 101?

I printed bytes from &MemPool[0] to just beyond &MemPool[99}.

Can you show the print function?

Maybe the problem lies there?

Using rdmd, I believe the code below demonstrates the situation.

import std.stdio;
void main() {
   immutable uint  MemSize=100;  // Memory size in bytes.
   uint counter;
   uint idx;
   ubyte* WkPtr;
   ubyte WkUbyte;

// Memory Pool
   ubyte[MemSize]  MemPool = 8;  // Initialised to 8 for 
debugging.

   WkPtr = &MemPool[0];

   counter = 1;
   while (counter <= 102) {

      idx = counter - 1;
        
          WkUbyte = *(WkPtr + idx);

      writeln("idx = ", idx, "WkUbyte = ", WkUbyte);

      counter = counter + 1;
   }
}
