Section and type conversion inside a function blows up section size

[mandar1jn]

Given the following pattern:

import std.mem;

#pragma array_limit -1

union StringToByteConverter<auto size>
{
    u8 data[size];
    str val;
};

fn main()
{
    u128 size = 2;

    auto fileSection = std::mem::create_section("file");

    StringToByteConverter<size> converter @ 0x0 in fileSection;

    converter.val = "a" * size;
};

it would be expected for the "file" section to have a size of 0x2. Instead it has a size of 0x40000002.

Moving the code to global scope (so outside of main) resolves this issue.
