There were many problems with -masm=intel, that were fixed for gcc-4.3 and
later by [1] and (many) followup patches. The change that you are looking for
is (gcc/config/i386/i386.c):

-      if (ASSEMBLER_DIALECT == ASM_INTEL && code != 'X' && code != 'P')
+      /* No `byte ptr' prefix for call instructions or BLKmode operands.  */
+      if (ASSEMBLER_DIALECT == ASM_INTEL && code != 'X' && code != 'P'

        {
          const char * size;
          switch (GET_MODE_SIZE (GET_MODE (x)))


However, this is just one of many changes to properly support -masm=intel, so
my best advice is to use gcc-4.3.x. This won't be fixed for gcc-4.2.
