I get core.exception.InvalidMemoryOperationError@(0) when I run the following
program on attached input file (XML).
import std.algorithm, std.file, std.stdio, std.string;
int main(string[] args)
{
if (args.length < 2) {
return 1;
}

foreach (line; File(args[1]).byLine())
linect += 1;
return 0;
}
Backtrace:
