There's a binary for use with Apache 2.2 on Windows in the download package. Any mechanism for getting a backtrace will require that symbol files (.pdb files) matching your Apache httpd build be present. I don't know how the Apache Lounge distributions accommodate that. Some other builds provide a separate .zip with the .pdb files, to be unpacked from the Apache httpd install directory prior to collecting problem documentation. > > -- > Mike > -- Born in Roswell... married an alien... http://emptyhammock.com/
