Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled

Hi there! I've tried to use your crate to apply the VarArgs list to it's associated format pattern, sadly it crashes with the runtime error:

Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled

I'm coding for an ESP32 embedded system, and I acquire the pattern + VarArgs by passing a function pointer to my code into esp_idf_sys::esp_log_set_vprintf(Some(esp_log_processor)).
The VarArgs are are passed with type [u32; 3usize] which im transforming like this to be able to use your library:

let args: VaList = core::mem::transmute(&args);

Maybe the underlying issue is related to esp-rs/rust#177

Can you help me? Thanks!

The Rust VaList impl has changed quite a bit since this issue was filed, perhaps this issue is fixed now? At any rate, since it's been a while I'm going to close the issue, but please feel free to reopen if you're still experiencing it and maybe I can help debug.

I've long moved on to other project but I'll be sure to come back and open another issue should I come back to it in the future and re-observe that issue.
