Hi Hanwei,

  Thanks for uploading the object files.  As I suspected however, on their own
they are not enough to trigger the bug.  For example a I tried test, based upon
the command line you provided, but with the system files and libraries removed,
and it worked:

  $ ld -pie --be8 -EB -z relro --hash-style=gnu --eh-frame-hdr -m
armelfb_linux_eabi -o g++-dg-lto-200811125.exe -plugin /usr/lib64/LLVMgold.so
-plugin-opt=mcpu=generic cp_lto_20081125_0.o cp_lto_20081125_1.o -e 0

  $ echo $?
  0

I suspect that the problem is related to the fact that you are targeting a
big-endian ARM system.  (The little-endian version tends to get more testing
than the big-endian version).

Given that you do have the full linker command line available, are you able to
run the linker under GDB and find out where the seg-fault is happening ?  And
what is causing it ? A null pointer ?  Accessing freed memory ?  Something else
?

Cheers
  Nick
