We now distribute a -symbols.zip file containing the precise debugging symbols corresponding to each released binary distribution. For the typical user, there is no need to download these archives.
These -symbols.zip packages contain the .pdb diagnostic symbol files (which correpsond to the distributed binary release) and can be used by nearly all modern Windows debugging tools, including the freely available WinDbg utility. They are most useful for the core developers to review crash dumps generated by Dr. Watson if Apache experiences a General Protection Fault. They also provide additional backtrace details in Dr. Watson crash log files, if they are installed into the Apache directory which is experiencing General Protection Fault or other crash issues.
If you don't understand a word of this, and a developer did not personally ask you to install them to help troubleshoot a problem, please trust that you do not need these files to install or run Apache Tomcat Connectors.
