The error message is bogus in any case.  Should be something like

test.d(11): no property 'someSymbol' for type 'B'

Though not technically an ICE, it seems to run into an infinite loop, effectively hanging the compiler, hence my adding ice-on-invalid-code.

With "int someSymbol;" uncommented code becomes valid, isn't it?

Well, obviously, but that isn't part of the bug being reported.  But I've just found that the same happens with it in.

And I've just had a closer look at the output, and realise it's the spellcheck facility seeing if there's something closely resembling the symbol it thinks is undefined.  So the loop isn't infinite.  Though DMD's notion of closely resembling puzzles me: if I reduce the name to "s" then it tries a total of 16130 of them.
