System: NetBSD weber.home 2.0 NetBSD 2.0 (WEBER_SB) #9: Sat Mar 18 14:36:03 EET 2006 jks@weber.home:/usr/src/sys/arch/i386/compile/WEBER_SB i386
Architecture: i386
Machine: i386
>Description:
	Some classes based on Resource (such as AttributeValue) contain
	virtual functions. An object of such a class begins with the vtable
	pointer, and the Resource object (counter) is offset by the size
	of the pointer (4). Hence the cast of (a pointer to) such an object
	to (a pointer to) Resource, introduced in "patch-ap", is wrong.
	(It typically leads to the corruption of the vtable pointer with
	ensueing SIGSEGV and core dump.)
>How-To-Repeat:

>Fix:
	Remove "patch-ap". The remaining compilation problems can be
	solved by delaying the instantiation of some templates in
	"parser_inst.cxx": replace "patch-ai" with the following
	(and corresponding changes in "patch-aj")
