Memory leak, missing a few bytes

Hello Gordon,

Received the Espruino. What i nice device! But i think i've found a mem leak.
Using 1v55.

The simple code:

// Callback function for din change

var cl=function(e) {  
    if (e.state===true) {
        print("Test...\n");
    }
};
var wid=setWatch(cl,B12,{repeat: false, debounce: 20});

After uploading process.memory(); shows 1766 free.

Each buttonpress decreases the free mem by aprox. 2 bytes.

Regards

Sacha

Those are not bytes - those are memory blocks, 20 bytes each.

Does trace() show the cause of the missing memory? That's what Gordon suggested I use to investigate my own memory leak issue.

@sacha - thanks! I'll get on to this - it looks like an issue with debounce. It should also pay attention to repeat:false :)

Hi Gordon,

Thanks. Had the same memleak befor using repear: true.
Let me know when it's fixed. I will doublecheck it.

If you remove debounce then the memory leak will disappear I think?

Hi Gordon,

I can confirme this. Without debounce there is no mem leak.
@drazzy thanks for the hint that this are junks of 20 bytes.

Should be fixed when 1v56 comes out - or on the 'latest' builds
