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
It's a bit interesting though.
The behavior seems to vary a bit between compilers.

As you can see, all have 100 valid values, but DMD seems to be
aligning to a multiple.
