Otherwise it won't. * unpacked pmwlite compressed programs might not work when compressed with UPX (this is a bug in pmwunlite) win32/pe -------- * writeable shared sections (`--force' *may* work) * certificates in the image * compressing files which contain a big BSS requires lots of memory during compression
