After spending some CPU cycles on compiling gcc, it looks like:

+Fri Apr 11 00:12:14 CEST 2003  Jan Hubicka  <[email protected]>
+
+       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?
