Hi Jori,

Would it be possible for you to create a test case using assembler
source files, rather than C source files ?  The output from gcc tends
to be very sensitive to the version of the compiler being used, so 
attempts to reproduce the problem may not always work.  (Especially
if the reproducer does not wish to download and install the ARM GNU
Toolchain).


Also - have you tested this problem using the newly released 2.38
version of the binutils sources ?  It may be possible that this bug
has already been fixed...

Cheers
  Nick
