+There is a rather scary and longstanding GCC bug [1] which causes
+instant crashes if a program defines a struct with function-pointers
+and that structure happens to be "packed".  Why anybody would want to
+do such a thing is beyond me, but suffice it to say that hpoj v0.91 is
+doing precisely that.  The current Debian/sarge package for hpoj is
+definitely affected (any attempt to scan an image results in an
+instant crash).
+
+A patch to work around the problem is attached.
+
+Perhaps the hpoj developers can tell us whether it was really
+intentional to have the #pragma pack(1) span all of <stdlib.h> and
+<xform.h>?
+
+Thanks,
