Embed file with absolute path from same drive as build panics compiler

[Sirius902]

Assume we run zig test on the below program from drive D on a Windows machine.

comptime {
    _ = @embedFile("D:/test.txt");
}

This will cause the following compiler panic:

Assertion failed at D:\a\1\s\src\stage1\util.hpp:229 in memCopy. This is a bug in the Zig compiler.thread 3332 panic: 
Unable to dump stack trace: debug info stripped

However if we try and embed from a different drive as the current such as C or E, then zig test gives the expected output.

.\src\main.zig:2:20: error: unable to find 'E:\test.txt'
    _ = @embedFile("E:/test.txt");
                   ^
.\src\main.zig:2:9: note: referenced here
    _ = @embedFile("E:/test.txt");
        ^

I did make a debug build of the zig compiler to get a stacktrace and here it is: https://pastebin.com/WsnzL85a.

I got it today too

Very odd, it doesn't reproduce on my box, I get the expected error:

C:\temp>type d:\test.txt
The system cannot find the file specified.

C:\temp>type foo.zig
comptime {
    _ = @embedFile("D:/test.txt");
}

C:\temp>zig version
0.9.0-dev.1444+e2a2e6c14

C:\temp>zig test foo.zig
.\foo.zig:2:20: error: unable to find 'D:\test.txt'
    _ = @embedFile("D:/test.txt");
                   ^
.\foo.zig:2:9: note: referenced here
    _ = @embedFile("D:/test.txt");
        ^
