Hello,

Consider this simple file 'byLineError.d':

import std.stdio;

void main()
{
    auto f = File("test");
    f.byLine.popFront();
}

When I compile:

dmd byLineError.d --- succeeds

dmd -inline byLineError.d --- fails with 'Internal error: backend/cod2.c 2200'

Using dmd version "DMD64 D Compiler v2.065" on Linux.

Am I doing something wrong, or is this a compiler bug? (Maybe f.byLine cannot be used in this manner?)

Thanks,
Saurabh

PS: How I came across this: I was trying to scan a file but skip the first line, so I wrote:

    auto f = File("test");
    f.byLine.popFront();
    foreach(line; f.byLine)
    {
        writeln(line);
    }

which gave the error.

PPS: This one uses an intermediate variable and succeeds:

void main()
{
    auto f = File("test");
    auto x = f.byLine;
    x.popFront();
}

The title should have read "Getting a compiler _error_ with '-inline'. Is this valid?"

:((

Internal compiler errors are always bugs. Please report it here: https://d.puremagic.com/issues/enter_bug.cgi?product=D

Oh okay. Will surely do that.

Make sure you add the tag "ice", which indicates it's a compiler crash. These get higher priority.
