Hi Masaki,

But ld combined .begin and .tail section to same program header
like this:
- - - - - -
Program Headers:
  Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
  LOAD           0x000054 0x00000000 0x00000000 0x00204 0x00204 R E 0x4

Section to Segment mapping:
  Segment Sections...
   00     .begin .tail
- - - - - -

Address 0x81 to 0x0ff are zero filled. This causes bus error
as there is no memory. Of course it is unexpected to me.

This sounds like a page size problem. Have you tried adding the "-N" option to the linker command line ?

Cheers
  Nick
