valid tile size causes build error

[EmilySillars]

Changes made to ConfigureForSnitch.cpp:
Replaced [0,56,100] tiling configuration with [0,40,25]:

if (funcOp.getName() ==
            "main$async_dispatch_9_matmul_transpose_b_1x161x600_f64") {
          l1Tiles[0] = 0;
          l1Tiles[1] = 40;
          l1Tiles[2] = 25;
        }

• I tried only changing the row dimension of the tile (leaving reduction dimension of 100 alone), and get the same error for tile size 40x100.
• Created PR reproducing this error here: tile-size-0-40-100-failure #146
