>Description:
	.init/.fini section handling is broken on all ELF platforms.

	ld.so should arrange for code in .init/.fini sections to be called
	as if it were part of _init()/_fini() functions.
>How-To-Repeat:
	Build crt{begin,end} from gcc distribution sources. Try to use and see
	failures due to not returning from .init/.fini code.

	Look at the .init/.fini sections:

	$ objdump --disassemble-all --reloc --section=.init crtbegin.o
 
	crtbegin.o:     file format elf32-i386
 
	Disassembly of section .init:
 
	00000000 <.init>:
   	0:   e8 54 00 00 00  call   59 <frame_dummy+0x1>
                        	1: R_386_PC32   .text

	$ objdump --disassemble-all --reloc --section=.fini crtbegin.o
 
	crtbegin.o:     file format elf32-i386
 
	Disassembly of section .fini:
 
	00000000 <.fini>:
   	0:   e8 fc ff ff ff  call   1 <.fini+0x1>
                        	1: R_386_PC32   .text
>Fix:
	Could linker scripts be used?
