Bug 13497 – [REG2.065] [ICE e2ir 1911] Array op compiler error

The two "main()" below both result in the same ICE e2ir.c:1911 using dmd 2067-devel --- void main() { int[1] a; auto tmp = (a[] * a[])[]; } /*void main() { double[] p = [-1, -2, -3, -4]; double[] origin = [1, 2, 3, 4]; auto shiftedPoint = (p[] - origin[])[]; }*/ --- Internal error: e2ir.c 1911 I'm opening this as a new issue but it may be a duplicate of 12179. System: Arch x86_64. DMD64 D Compiler v2.066.0 or DMD64 D Compiler v2.067-devel-5606406 Cheers, gc

It should emit an error: test.d(3): Error: Array operation a[] * a[] not implemented This is a regression. Introduced in https://github.com/D-Programming-Language/dmd/pull/2960

Sorry my fix was incomplete. I found some unfixed cases. void main() { int[1] a; //auto b1 = (a[] * a[])[]; // error, expected auto b2 = (a[] * a[])[0..1]; // Internal error: e2ir.c 1911 int[] c; //c = (a[] * a[])[]; // error, expected c = (a[] * a[])[0..1]; // Internal error: e2ir.c 1911 }
