Abstract
The precise detection of errors in computer programs using the hardware watchpoint mechanism found in computers is disclosed. In one embodiment, a software detection phase of a method detects the approximate location of an error, generating information regarding this approximate location. In this embodiment, a hardware watchpoint phase of the method detects the precise location of the error based on the information generated by the software detection phase, generating information regarding the precise location. Finally, in this embodiment of the invention, a debugger phase of the method identifies the statement in the computer program causing the error, based on the information generated by the hardware watchpoint phase.
