0xe90ed750e0 is the string pointer on my machine (not yours). You can easily see the Int32Wrappers, with the extra 4 bytes of padding that turned the size into 24 bytes. Go back to the struct and put the string last. Repeat and you'll see the...

Bash continuation lines
...is creates two arguments to echo and you only want one, then let's look at string concatenation. In bash, placing two strings next to each other concatenate:

So a continuation line without an indent is one way to break up a string:

A given compiler and a given ABI will need to choose specific sizes for int and bool and when, like in your case, these are different sizes they may generate slightly different code, and at some levels of op...
