You can obtain the
pdb debugging symbols for the standard ActivePerl builds at
http://downloads.activestate.com/ActivePerl/Windows/. To use these, browse this site until you find the appropriate zip file containing the symbols (eg, ActivePerl-188.8.131.522-MSWin32-x86-283697-symbols.zip), and unpack this in the same top-level directory where Perl was installed (eg, C:\Perl). Debugging tools like Dr. Watson, as well as Visual Studio if you have it, will then use the information in these symbol files to help pinpoint where and why a crash occurred.
