Here's the process I use for reference. Let me know if you have suggestions for improvements, otherwise I'd like to put it up on the Wiki as the recommended process to follow.
1. using the cross-build result pages currently at http://people.apache.org/~sebor/stdcxx/results/builds/ scan result page for an uncharacterized error (build problem, abnormal exit, unexpected difference in example output) 2. check other versions of the same platforms for the same error 3. check 4.2.0 results for the same error on the closest available platform http://people.apache.org/~sebor/stdcxx-4.2.0/results/builds/ 4. file an issue for the problem * if the problem is platform-specific, mention the platform in the Summary (e.g., [Sun C++ 5.8/Solaris/SPARC]) * if it's a regression from 4.2.0, check the Regression box, set Affects Version/s to trunk, and schedule for 4.2.1 * otherwise (not a regression), set Affects Version/s to 4.2.0 * include as much detail in Description as possible (use the {noformat} tag to disable Jira formatting of command lines, code snippets, and program output) * set the Severity field as appropriate * try to asses the Priority of the problem based on the platform (Primary, Secondary, Best Effort), the Severity of the problem (signal is usually worse than compilation error), and the area of the library it affects (an error in a test due to a compiler bug is of lower priority than a runtime error pointing to std::string) * if possible, take a guess at the effort required in fixing the problem by setting the Original Estimate Martin
