           Summary: __traits(compiles) + mixin
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: regression
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: callumenator gmail.com



DMD2.062:

http://forum.dlang.org/thread/vnnmmwhoyrdtbglqxqkz forum.dlang.org#post-tdojcnsrtkygjbhwegph:40forum.dlang.org

import std.conv;

void main()
{
    enum s = "`1`.to!int;";
    enum c = __traits(compiles, mixin("{auto a = new "~s~";}")); // line 1
    mixin("auto a = "~s~";");  // line 2
}

Long errors about instantiating std.conv.to!(int).to!(string). Swap lines 1 and
2 and compilation succeeds. This worked in 2.061. Possibly related to issue
9017.

fix Issue 9650 - __traits(compiles) + mixin

I couldn't minimize test case, but the bug fix is obvious.

The bug had been hiding for a long time, but recent Phobos change
(https://github.com/D-Programming-Language/phobos/commit/2a88fea7867f33fd1cf15c2dca7790a3c8aea474)
had exposed the bug.

When a mixin expression gets invalid code string, the parsing error had not
handled correctly. In such case, it had generated *invalid* AST instead of
returning ErrorExp. I guess that the invalid AST would report weird error in
later semantic analysis.

I think that both CompileDeclaration and CompileStatement do not have same
problem. So they are not changed.
