  I tried compiling GMP 4.2.4 with ABI=mode32 on gcc40.fsffrance.org

  Note that everything is ok with ABI=32.
  
What a naughty compiler, generating assembly code that the assembler
doesn't understand!  (This is not GMP related, it is easy to trigger
with plain C code.)

  Is there any reason why ABI=mode32 is not tested at all on
  http://gmplib.org/devel/testmachines.shtml?
  
Just time constraints I suppose, and test system limitations.
