Spot the syntax error.

No, it's not the squiggly red line.

It's not marked.

(Faulty line is highlighted as a hint)

Excerpt from a VHDL code file (lines 104 through 120); code below for clarity. Line leading with `debug_ila_0` is (wrongly) marked with a squiggle (`ila_0` does exist, and this is a VDHL 2008 file, so this entity syntax is correct).

The clear error is in probe3(0), where the association arrow points in the wrong direction. No squiggle here.

Code:
debug_ila_0: entity ila_0
port map (
clk => slow_clk,
probe0(0) => i2c_scl_i,
probe1(0) => i2c_scl_t,
probe2(0) => i2c_scl_o,
probe3(0) <= i2c_sda_i,
probe4(0) => i2c_sda_t,
probe5(0) => i2c_sda_o,
probe6(0) => i2c_ena,
probe7(0) => i2c_rw,
probe8(0) => i2c_busy,
probe9(0) => gpio_test,
probe10 => i2c_addr,
probe11 => i2c_data_wr
);
