An unsolvable problem, clearly, as it is inconceivable that the 
user could set a  heap size.

Don't believe anyone that would tell you this could boils down to 
a simple call to a function, such as GC.setHeapSize(XXXX), they 
are clearly manipulating you.

Let me tell you a secret. most modern languages use an hybrid 
approach as the one I described, and even old one have been 
repurposed to use that when possible (for instance python).

Ho, damn, a hybrid approach that allocates on the stack or the GC 
and frees instead of leaking. Who could have though of that?

How the strawman screaming in between you hear doing?

With all due respect, you clearly are not able to address the 
points made in the discussions you are participating in. It's 
harsh, but it's true. You shouldn't be making statements about 
others losing their mind.
