ERR_BUFFER_OUT_OF_BOUNDS exception on ref.reinterpret call

[avivsalman]

Hi, I have problem, when I'm using ref-napi 1.5.2 its work fine, but I need the napi libs for compatibility issue with electron and last node versions too, and change to 3.0.1 then I got this error when use reinterpret inside a ffi.Callback function.

captureCallback = ffi.Callback('void', ['pointer', 'uint', 'uint', 'pointer'], (ctx: any, rsv: number, dtSize: number, dt: Buffer) => { const dtReinterpreted = new dpfpdd_capture_callback_data_0(ref.reinterpret(dt, dtSize)); ..... ..... });

I hope it is useful, if need anything else please update me :)

What is dtSize in that example? You can’t use reinterpret anymore to increase the size of the underlying ArrayBuffer.

I have this issue too with v3.0.1. Now it works with nodejs v12 locked version 1.5.2. But led core dump with nodejs v14.
