Problem with dlmalloc v0.2.5

[obioma]

Hi,
after updating the complete rust tool chain the following error happened when a message was received. I'm not sure if the real root cause lies within leptos_use or rather somewhere else.

What I can say is that after manually enforcing dlmalloc v0.2.4 via an entry in cargo.toml and using

//main.rs
#[global_allocator]
static ALLOCATOR: dlmalloc::GlobalDlmalloc = unsafe { dlmalloc::GlobalDlmalloc};

it did work again. Utilising

#[global_allocator]
static ALLOCATOR: talc::TalckWasm = unsafe { talc::TalckWasm::new_global() };

resulted in an similar error - also with a validation assertion.

While it is working now, I think it is worth to understand the underlying root cause, but I must admit I'm not able to dig deeper to to lack of knowledge. Maybe somebody from leptos_use or even leptos community has an idea.

Thx

Here the error message.

panicked at /rust/deps/dlmalloc-0.2.5/src/dlmalloc.rs:1182:13:

Uff! I doubt that this originates from within leptos-use as something simple like allocating a String seems to fail. Thanks for reporting this. I'm going to close the issue because I have not the slightest idea what to do here except wait and see if others have the same issue.

Thx for replying. Agree. When searching around for similar errors there was something with leptos update referenced, and a potential source was named by @greg Johnston. But I must admit I didn't understand.
I also looked at leptos_use code, and my impression was it happens when the message signal is touched -> leptos or dlmalloc problem. But to be on safe side I started with leptos_use - you ;-).
Now I'm not sure if I shall raise within leptos or wait as you suggested. For the next days I wait.
