Problem with Fields counting involving user-defined malloc. struct S { int a, b, c; } x, *s; struct T { float f, g; } y, *t; /* x and y are initialized elsewhere in the program */ void a() { s = (struct S * ) my-malloc(sizeof(struct S)); *s = x; } void b() { t = (struct T * ) my-malloc(sizeof(struct T)); *t = y; } char *my-malloc(int size) { char *p = malloc(size); return p; } NoFields counting is preferred, and the results in Section 4 are reported using this scheme, though Figure 24 offers results using Fields counting and shows how this choice can influence the results reported.

Programs may explicitly allocate such complex data structures using the macro malloc but are not allowed to explicitly de-allocate the structures; this is done implicitly, through garbage collection.
A few times I've seen as a result those developers taking all their stack-allocated buffers and turning them into heap-allocated ones (that is, allocated by malloc).
To allow a process in an embedded system to run until malloc fails can cause the entire system to crash.
The functions malloc and free perform dynamic memory allocation for the operating system.
The malloc field holds a pointer to a memory arena [Vo 1996] that is used to allocate memory regions from this space.
[1989], and Landi and Ryder [1992] use the k-limiting approach [Jones and Muchnick 1981], and thus distinguish up to k objects created at the same malloc statement.
However, the non-pinned memory is the memory which is allocated by using the malloc function.
The two exceptions to this are the unpack and malloc instructions, which are discussed below.
However, recent operating systems have optimized commonly used buffer management system calls, such as bcopy and malloc. The time spent in these calls is now quite small and is not a significant factor in the performance of Totem.
