veb: memory leak

[esquerbatua]

Describe the bug

veb leaks memory, also maybe picoev

Reproduction Steps

With this code:

module main

import veb { Result }

pub struct Context {
    veb.Context
}

pub struct App {
}

fn main() {
    mut app := App{}
    veb.run_at[App, Context](mut app, veb.RunParams{
        host: '0.0.0.0'
        family: .ip
    }) or { panic(err) }
}

fn (app &App) index(mut ctx Context) Result {
    return ctx.json('')
}

compile it with: v -cg -cc gcc -keepc -gc none /home/esquerbatua/git/breakV/jsonx.v -o vebLeak run it with: heaptrack ./vebLeak make a few requests and close the app, then run: heaptrack --analyze <generated .zst file>

Expected Behavior

Run without any memory leak

Current Behavior

Memory leaks, even with boehm.

Possible Solution

Manual free in vlib functions of picoev and veb?

How curious, it seems that there are no more memory leaks, I keep it open until veb parallel is complete and I check again.
