[BUG] No warning on >100% RAM usage

[non-bin]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

My original title for this was "Compiling with FT_MOTION causes firmware to lockup during boot", until I noticed
echo: Free Memory: -29396 PlannerBufferBytes: 1600 Negative free memory?
RAM: [==========] 193.5% (used 15849 bytes from 8192 bytes) 193%?

echo: Last Updated: 2023-11-21 | Author: (Alice, Creality Ender-5 Plus)
echo: Compiled: Nov 22 2023
echo: Free Memory: -29396  PlannerBufferBytes: 1600 <------------------------------- Negative free memory?
//action:notification Print Paused
echo:SD card released
echo:busy: processing

Then it locks up to the point were disconnecting and reconnecting serial console doesn't reset it, it has to be powered off and on

[EvilGremlin]

This is not a bug, compiler/linker don't throw an error on RAM overflow. Won't be of much use because not everything is accouted for and you need to have some RAM free (500B at least)
Not sure if we can parse terminal output and throw error with script, probably no.

[non-bin]

Fair enough, maybe I'll report it to pio then?

[EvilGremlin]

It's not really pio either, it's gcc area. But pio could implement parse&error indeed.
