  My problem is the small testcase: I am trying to reproduce with few
 source files generating libraries and it works normally.
 Probably a bug report begining with "download linux-2.6.13.tar.bz2" will
 not be useful.

 I am wondering about the name of this file: arch/i386/kernel/built-in.o
 When generating Linux, it is a linked library and should be called
 arch/i386/kernel/built-in.a (it contains all the objects in
 arch/i386/kernel/*.o). If it were only the result of compiling
 a file named arch/i386/kernel/built-in.c, it would be logical to unify
 the local and the global memcpy symbol.
 Would that ring a bell to someone - is the treatment different depending
 on the extension of the file?

  Thanks,
  Etienne.
