// This source code demonstrates a test suite for memory allocation using custom `malloc`, `realloc`, and `calloc` in the `rtest` framework.
|
|
// It performs a series of memory allocation and deallocation operations, checking the count of allocations and deallocations to ensure
|
|
// proper memory management and detect any leaks or errors.
|
|
|
|
// Dependencies:
|
|
// This code relies on the custom libraries `rtest` and `rmalloc` specific to this testing framework.
