Yes, it does "help" to trigger the issue by adding a bit to loader.efi size and
via some change to screen update - getting text on screen via simple text
output protocol does cause memory allocation by uefi firmware.

The first visible related error is memory allocation to store efi memory map
just before we switch off BootServices, however simple switch to alternate
memory does not chenge anything there, so it must be something more going on.

My guess is that the best option still would be to hook up to gdb stub and try
to catch where we are blowing up and then we also know why exactly. Right now
we can only guess.
