So far I have been able to get a class and heap allocated struct
to allocate and deallocate manually on an STM32F407 MCU. Array
bounds checking works but so far just logs the error in my IDE
and hangs. Abstract classes work too. Interfaces are giving me
trouble for some reason - they crash LDC2 1.23.0.
Going to add some proper support for D's assert(...) and array
bounds checking to make things a little easier.
