Some pngs will cause unexpected exit

[sbfkcel]

Reading some files based on docker alpine will cause unexpected exit.

The attached icon is a test png.

test.js

const libpng = require('node-libpng');
let result = libpng.readPngFileSync('./icon.png');

console.log(result);

icon.png.zip

Are some PNGs working? Or is it failing with all?

[sbfkcel]

Some PNGs failed. Not all are invalid.

After confirming the test, when the "Interlace" option is checked, it will cause unexpected errors.
