What are "Most Frequently Reported Bugs"?

The Most Frequent Bugs page lists the known open bugs which are reported most frequently. It is automatically generated from the GCC Bugzilla database every 24 hours, by counting the number of direct and indirect duplicates of bugs. This information is provided in order to assist in minimizing the amount of duplicate bugs entered into GCC Bugzilla, which saves time for Quality Assurance engineers who have to triage the bugs.

How do I use this list?

Review the most frequent bugs list.
If your problem is listed:

Click on the bug number to confirm that you have found the same bug, and comment if you have additional information or move on with your testing of the product.

If your problem not listed:

Try and locate a similar bug that has already been filed.
If you find your bug in GCC Bugzilla, feel free to comment with any new or additional data you may have.
If you cannot find your problem already documented in GCC Bugzilla, file a new bug.
