User(s) can reproduce this bug
'Phx.Common.Opcodes.Alloca' not implemented for X86 architecture. Using it leads to assertion failures.

But is there any normal way to allocate arbitrary byte array on stack?
In C# can do this via 'stackalloc type[size]'
In Visual C++ it can be done using '_alloca' function.
