This work deals with some issues concerned in the debugging of concurrent programs. A set of desirable characteristics for a debugger for concurrent languages is deduced from a review of the differences between the debugging of concurrent programs and that of sequential ones. A debugger for a concurrent language, based upon CSP, is then described. The debugger makes it possible to compare a description of the expected program behavior to the actual behavior. The description of the behavior is given in terms of expressions composed by events and/or assertions on the process state. The developed formalism is able to describe behaviors at various levels of abstraction. Lastly, some guidelines for the implementation of the debugger are given and a detailed example of program debugging is analyzed.
