cgen: `-autofree` fails

[malisipi]

Describe the bug

The code can work without -autofree but if you try to compile with -autofree, your code will not be compiled.

import strconv

fn color_code_to_rgb(color string) []int {
	clr := color.replace('#', '')
	return [int(strconv.parse_int(clr[0..2], 16, 0) or { return [0, 0, 0] }),
		int(strconv.parse_int(clr[2..4], 16, 0) or { return [0, 0, 0] }),
		int(strconv.parse_int(clr[4..6],
			16, 0) or { return [0, 0, 0] })]
}

println(color_code_to_rgb('#abcdef'))

Expected Behavior

Works fine and writes the output to console

[171, 205, 239]

Current Behavior

Compiler fails with

[malisipi@malisipi-20351 ~]$ v -cg -autofree free.v 
/tmp/v_1000/free.11594424565698986927.tmp.c:12879: error: cannot convert 'typedef struct string' to 'int'
builder error: 
==================
C error. This should never happen.

Reproduction Steps

Compile the code with v -autofree file_name.v

Adding -g points to the line with the first call to strconv:

$ v -autofree -g run free.v
/tmp/v_1000/../../../../../../home/jalon/free.v:5: error: cannot convert 'typedef struct string' to 'int'

The C code that was generated by V. I'm not understand correctly C code since I don't know cgen how works. But it is clearly the code has missing characters (like ), }) and wrong usage of new_array_from_c_array_noscan (at 7. line)
