Subject: bug in the way Linux loads elf files...

It seems that the linux kernel does not exactly conform to the TIS elf
standard.  as follows...

I have a small asm source file that a assemble with nasm

  [section text]
  global _start

_start:
  mov eax, 1
  int 0x80

after linking i end up with a elf executable which does nothing
execept terminate which of course works perfectly fine.

If however i modify the .text sections program header to make the
memory size larger than the file size the process is killed before it
is even run.  I have not tracked down where this happens.

  Type            Offset       VirtAddr         PhysAddr     FileSiz
MemSiz  Flg Align
  LOAD           0x000000 0x08048000 0x08048000 0x0007b 0x01000 R   0x1000

i patched MemSiz to be larger than FileSiz which should work but does not.
