A method for diagnosing software crashes includes retrieving a stack-trace from at least one of a new problem report, updated problem report, and authorized analysis report from a repository. A vector is automatically created from the retrieved stack-trace using the function name and associating the resultant vector with the problem report and authorized analysis reports. Vector space modeling is used to calculate the angles between the resultant vectors to determine similarities. Similar problem reports and authorized analysis reports are grouped into similar sets using a maximal cliques process. New software crashes are automatically diagnosed by extracting the stack-trace from a new problem report of the new software crash, and selecting a potential solution by searching the grouped problem reports and authorized analysis reports for a stack-trace similar to the new stack-trace.
