How to alloc a executable memory buffer?

Question

I would like to alloc a buffer that I can execute on Win32 but I have an exception in visual studio cuz the malloc function returns a non executable memory zone. I read that

At compile time, the linker will organize your program's memory footprint by allocating memory into data sections and code sections. The CPU will make sure that the program counter (the hard CPU register) value remains within a code section or the CPU will throw a hardware exception for violating the memory bounds. This provides some security by making sure your program only executes valid code. Malloc is intended for allocating data memory. Your application has a heap and the heap's size is established by the linker and is marked as data memory. So at runtime malloc is just grabbing some of the virtual memory from your heap which will always be data.

I hope this helps you have a better understanding what's going on, though it might not be enough to get you where you need to be. Perhaps you can pre-allocate a "code heap" or memory pool for your runtime-generated code. You will probably need to fuss with the linker to accomplish this but I don't know any of the details.
