import std.stdio;
import std.file;
import std.process;

void test()
{
    auto file = File("test.txt", "r");
    foreach (line; file.byLine)  // remove and bug goes away
    {
    }
}

void main()
{
    system("echo blabla > test.txt");  // create file externally
    test();
    std.file.remove("test.txt");
}

std.file.FileException at std\file.d(549): test.txt: The process cannot access the
file because it is being used by another process.

Btw this has nothing to do with that system call, you can remove it if you have
a test.txt file.

As a workaround I can use scope(exit){ file.close(); }
