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,
|
