Bug 13208 – [ICE](e2ir.c 2077) with array operation

Internal Error e2ir.c 2077 is thrown if line 40 of the code here is included. http://pastebin.com/RefD9hzg Separating the array operations as seen here: http://pastebin.com/aX6edUvg eliminates the error. #D on freenode tells me this error should never be thrown, so I thought I would submit it.

Reduced: void main() { int[][] a; a = [a[1][] - a[0][]]; } Internal error: e2ir.c 1910

Adding this chunk inside ArrayLiteralExp::semantic fixes it for(size_t i = 0; i < elements->dim; i++) { Expression *el = (*elements)[i]; if (isNonAssignmentArrayOp(el)) { el->error("array operation %s without assignment not implemented", el->toChars()); return new ErrorExp(); } } But I'll leave this to Kenji as IIRC he did this rest of this checking and would know best. I'm sure there are other places this check needs to be added.

This is a regression from 2.065, as same as bug 12179 and bug 12769. https://github.com/D-Programming-Language/dmd/pull/3818
