putting a bp on d, i does not show up in the locals or auto list.

adding i in the watch says symbol not found?!?

j and c show up.

there is a for loop that uses i later. Changing it to ii lets i show up?!?!

Seems somehow they are being canceled out.

Not if it's just two loops or what, but it seems the id's collide somehow.

Please provide a compilable example.

BTW: bugs are better reported at https://issues.dlang.org/enter_bug.cgi so that it's easier to keep track of progress.
