Detailed Description

Unit test for the internal arena allocator.

This test file validates the core functionality of the infix_arena_t memory manager. Since the arena allocator is an internal component, this test must include the arena.c source file directly to access its functions. It also defines the infix_* memory macros to use the standard malloc, etc., to avoid interference from the fault-injection allocator in other tests.

The test verifies:

• Creation/Destruction: infix_arena_create and infix_arena_destroy work as expected.
• Basic Allocation: infix_arena_alloc returns a valid, non-null pointer.
• Alignment: A pointer allocated with a specific alignment is correctly aligned.
• Zeroed Allocation: infix_arena_calloc returns a block of memory that is properly zero-initialized.
• Error Handling: When an allocation request exceeds the arena's capacity, infix_arena_alloc correctly returns nullptr and sets the arena's internal error flag.
