Is the xfdmaster.library support broken in the OS4 xpkmaster.library because when I set XPK_UseXfdMaster to TRUE in xpkExamineTags() and xpkUnpackTags() calls in XFH-Handler it causes crashes (DSI then ISI) in xpkmaster.library? Using Ranger I can see that xfdmaster.library has been loaded so at least it is doing something with it.
I'm using the m68k xfdmaster.library from Aminet (manually installed) with Chris Young's xfdmaster.l.main glue file also from Aminet. xfdmaster.library is disabled in Compatibility prefs as is recommended and it seems to work fine when I use xfdDecrunch to decrunch files from the CLI.
