The execution engine crashes on the LLVM IR generated by MLIR lowering on IR that uses a "sparse" encoding of a complex32 buffer. I could narrow it down to the following reproducer:
module attributes {llvm.data_layout = ""} {
memref.global "private" constant @"__constant_32xcomplex<f32>_0" : memref<32xcomplex<f32>> =
sparse<[[1], [28], [31]],
[(1.000000e+00,0.000000e+00), (2.000000e+00,0.000000e+00), (3.000000e+00,0.000000e+00)]
> {alignment = 128 : i64}
llvm.func @entry() {
%0 = memref.get_global @"__constant_32xcomplex<f32>_0" : memref<32xcomplex<f32>>
llvm.return
}
}
![]()
