Ticket <URL: https://rt.cpan.org/Ticket/Display.html?id=82916 >If a compiled script is killed while writing out its archive, a partially-written cache file may result (often a short extraction of libperl.so, as that tends to be the largest file in the archive). The present code in myldr/boot.c:extract_embedded_file() is willing to write a missing file, but not overwrite a partially-written file (one where the size in the archive differs from the size on the filesystem), resulting in an abort with a fatal "file exists" error. The attached patch permits the loader to overwrite a corrupt file. I added a warning to stderr to report this condition, but that may or may not be appropriate. It was a useful diagnostic aid for my purposes.
