[Critical] 3.1.1 and dev version crash randomly on windows,maybe code bug

[eebssk1]

I'm getting random crashes on windows with 3.1.1 and latest dev version.
I managed to recompile the project and convert gnu debug data to pdb.
This is the snapshot when the crash happens

Aparently the return register gets corrupted when process_udp return because of wrong packet.

local struct data looks like garbage too.

udp_size parameter looks like a big random number.
