<pre>In <a href="https://github.com/JuliaLang/julia/issues/41440#issuecomment-932016347">https://github.com/JuliaLang/julia/issues/41440#issuecomment-932016347</a> and
<a href="https://github.com/JuliaLang/julia/issues/42295">https://github.com/JuliaLang/julia/issues/42295</a> we've noticed a recurring issue
related to the large code model for the new Apple Silicon chips.
The issue is that the Orc JIT will crash if the memory allocator does not
allocate sections within 4GB of each other (which the default allocator does
not).
Possible relevant lines of code:
