 #### O1HEAP_ASSERT(x)
 
 The macro `O1HEAP_ASSERT(x)` can be defined to customize the assertion handling or to disable it.
-To disable assertion checks, the macro should expand into `(void)(x)`.
-If not specified, the macro expands into the standard assertion check macro `assert(x)` as defined in `<assert.h>`.
