           Summary: DMD asserts using delegate and type inference
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: doob me.com



When I try to use a delegate as template parameter and type inference DMD
asserts with this message:

Assertion failed: (!vthis->csym), function toObjFile, file glue.c, line 686.

https://github.com/D-Programming-Language/dmd/blob/master/src/glue.c#L686

I haven't been able to find a reduced test case but this is the code that
fails:

https://github.com/jacob-carlborg/phobos/blob/terminal/std/event.d#L113

If I changed that line to:

eventHandlers = .remove!((e) { return e == eventHandler; })(eventHandlers);

Or

eventHandlers = .remove!(e => e == eventHandler)(eventHandlers);

The assert is triggered. I'm using:

DMD: b41a2c360f09b83e4de6951f1e7538372319704f
Druntime: b41a2c360f09b83e4de6951f1e7538372319704f
Phobos: b93e9c9fd47fe309bb422408cbedc5897d87c368

I'm compiling on Mac OS X for 32bit.

This is probably a duplicate of bug 4129.
Two others which ICE at the same place are bug 6896 and bug 4481.

Jacob - since 4481 and 6896 appear to be fixed, and 4129 is D1 only, can you
see if this still is a problem here?

I cannot reproduce this error anymore.
