Abstract-Bounded model checking of C++ programs presents greater challenges than that of C programs due to the more complex features that the language offers, such as templates, containers, and exception handling. We present ESBMC++, a bounded model checker for C++ programs. It is based on an operational model, an abstract representation of the standard C++ libraries that conservatively approximates their semantics. ESBMC++ uses this to encode the verification conditions using different background theories supported by an SMT solver. Our experimental results show that our approach can handle a wider range of the C++ constructs than existing approaches and substantially reduces the verification time.

The software development process for embedded systems is getting faster and faster, which generally incurs an increase in the associated complexity. As a consequence, consumer electronics companies usually invest a lot of resources in fast and automatic verification processes, in order to create robust systems and reduce product recall rates. Because of that, the present paper proposes a simplified version of the Qt framework, which is integrated into the Efficient SMT-Based Bounded Model Checking tool to verify actual applications that use the mentioned framework. The method proposed in this paper presents a success rate of 94.45%, for the developed test suite.Index Terms-Qt framework, Bounded Model Checking.
