Lwip crashes when processing a big image multiple times in sequence

(Requires "when" module)

Im on a 64bit windows 7 running node 12. The image is from: http://placehold.it/3000x3000 Any thoughts?

[peeter-tomberg]

The exit code is 3221226356 ( 0xC0000374 ), which seems to be an error code for heap corruption?

[peeter-tomberg]

Any thoughts on this?

Interesting. Does it exhibit the same behaviour with node 10?
