 After spending some CPU cycles on compiling gcc, it looks like:
 
 +Fri Apr 11 00:12:14 CEST 2003  Jan Hubicka  <jh@suse.cz>
 +
 +       PR inline-asm/8803
 +       * function.c (instantate_virtual_regs):  Verify that all ASM
 statements
 +       match after the virutal regs instantiation.
 +
 
 
 gcc/gcc/function.c:
 
           instantiate_virtual_regs_1 (&CALL_INSN_FUNCTION_USAGE (insn),
                                       NULL_RTX, 0);
 +       
 +       /* Past this point all ASM statements should match.  Verify that
 +          to avoid failures later in the compilation process.  */
 +        if (asm_noperands (PATTERN (insn)) >= 0
 +           && ! check_asm_operands (PATTERN (insn)))
 +          instantiate_virtual_regs_lossage (insn);
        }
 
 triggered my regression.
 
 Removing that patch from 3.3.0 makes my code compile
 again - I'm happy :-)
 
 Maybe its possible to add another condition to that if statement?
