Do not hesitate to ask for more info!!!! Um, at least in my case, none of your attachments are very useful for identifying a problem. Please just send the Installation file generated by configure (M-x describe-installation). The code above is one place where the pointer tag bits are being diddled with. You are apparently using the system malloc (using the old GNU Malloc distributed with XEmacs might be easier and it might not). Have you tried building with -DUSE_MINIMAL_TAGBITS? The System malloc on Linux (the new GNU malloc) has a tendency to return pointers which can collide with the usual Lisp tagbits. Check the documentation for malloc and make sure that it does not use mmap. If it does, you will have to arrange to have it turned off while XEmacs is dumping or you will lose. See the code guarded by `#ifdef DOUG_LEA_MALLOC' for clues on how to do this with one implementation.
