Description bearophile_hugs 2010-04-21 13:48:33 UTC 
This D2 code:

import std.stdio: writeln;
void main() {
    int[0] a;
    writeln(a);
}


dmd 2.043 shows:

[...]\dmd\src\phobos\std\format.d(2040): Error: array index 0 is out of bounds obj[0 .. 0]
[...]\dmd\src\phobos\std\format.d(2040): Error: array index 0 is out of bounds [0..0]

Fixed in svn r1546.
Comment 2 bearophile_hugs 2010-06-14 04:39:14 UTC 
Reopened. Phobos needs to be debugged with warnings on. If I compile that program with:

dmd -w test.d

DMD 2.047 prints:
...\src\phobos\std\format.d(2040): Warning: statement is not reachable
...\src\phobos\std\format.d(2041): Warning: statement is not reachable
Comment 3 Shin Fujishiro 2010-06-14 08:42:42 UTC 
Okay, I fixed it in svn r1642.
