`int depth = strtol(*str + 1, str, 10);`
`**str` holds the words in the VGSL specification, and `*str` holds a single word, lets say, `Fr64`. Now, the `strtol` function modifies `str` to point to the first character which a non-digit number, and assumes that ` *str+1 ` points to a number (of valid integer format) as a string (automatically skipping all the white spaces, and no other characters), where in reality, it seems to point to `r` in `Fr164`.This is a bad argument, which results in strtol returning 0.
` strtol (*str + 2, str, 10)` should be passed instead.

Wrong file data could give a large value for the number of vector elements
