Benchmark Data
This benchmark is located in crv.liflab.ca@/home/e-acsl/crv16_benchmarks/c-implicit-track/stack-read
The Trace Part
E-ACSL has no notion of trace
The Property Part
Informal Description
The property explored by this benchmark relates to memory safety and more specifically to a spatial error on a program's stack where a pointer P to an allocated memory block A is used to read from a properly allocated memory location which address does not belong to A.
The scenario explored by this benchmark is as follows. Two character arrays are allocated on a program's stack. The arrays are filled with data and the difference between their start addresses is computed. This difference is then used to print the contents of the second buffer using a pointer to the first buffer.
Demonstration Traces
Formal Specification
The formal specification is given using ACSL
/*@ assert \base_addr(p) == \base_addr(p + i); */
where p is of pointer type and i is of integral type.
