[ Picked text/plain from multipart/alternative ]
There doesn't appear to be any main engine API function calls from anywhere
but the main thread. The additional threads are worker threads that only
create connections and poll the IO.
To create a new connection, there's a pending list that is dumped to the
other thread behind a critical section, and all finalization is dumped to a
pending finalize list to also be cleared out (deleted) from the main thread
behind a critical section. I'm trying to find ANY possible "new" and
"delete" calls that might take place across the threads that shouldn't.
Should I be including the standard:
// memdbgon must be the last include file in a .cpp file!!!
#include "tier0/memdbgon.h"
and is there an incompatible CRT for code generation?
