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>?
