Bug 8082 – Invalid error messages based on module compilation order

main.d that references an undefined function: module main; void main() { test(); // invalid call } and util.d: module util; import std.algorithm; bool canFindAny(string[] inputs, string target1) { foreach (input; inputs) { if (target1.canFind(input)) return true; } return false; } $ dmd main.d util.d main.d(4): Error: undefined identifier test D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d(2837): Error: template std.algorithm.find does not match any function template declaration D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d(2837): Error: template std.algorithm.find cannot deduce template function from argument types !("a == b",ubyte[],ubyte[])(ubyte[],ubyte[]) D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d(2836): Error: template instance find!("a == b",ubyte[],ubyte[]) errors instantiating template Only the first error message should appear. If you comment out the call to "test()" in main.d, all errors are gone. Note that the order of compiling the modules changes the behavior, see: $ dmd util.d main.d $ main.d(4): Error: undefined identifier test $ dmd main.d util.d $ main.d(4): Error: undefined identifier test D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d(2837): Error: template std.algorithm.find does not match any function template declaration D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d(2837): Error: template std.algorithm.find cannot deduce template function from argument types !("a == b",ubyte[],ubyte[])(ubyte[],ubyte[]) D:\DMD\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d(2836): Error: template instance find!("a == b",ubyte[],ubyte[]) errors instantiating template

Seems to be fixed in 2.063.2.
