CORTEX_MPU_LPC1768_GCC_RedSuite Demo issue

What version of gcc toolchain build this demo tested against ?
I tried LPCXpresso v3.6.3   (should be very similar to RedSuite as stated in demo name).
E:lpcxpresso_3.6.3_317Toolsbin>arm-none-eabi-gcc.exe --version
arm-none-eabi-gcc.exe (Code Red/Red Suite/2009_01_C) 4.3.3
...
Here is the fragment from RTOSDemo_RDB1768.map:
privileged_functions
        0x00001798  0x5d4 ./src/FreeRTOS/portable/GCC/ARM_CM3_MPU/port.o
        0x000018d8      xPortStartScheduler
        0x00001990      xPortSysTickHandler
        0x0000193c      xPortPendSVHandler
        0x00001930      vPortEndScheduler
        0x00001810      vPortSVCHandler
        0x00001798      pxPortInitialiseStack
        0x00001b8c      vPortStoreTaskMPUSettings
.text       0x00001d6c  0x51d6
        0x00004000      . = (__privileged_functions_start__ + _Privileged_Functions_Region_Size)
 *fill*     0x00001d6c  0x4000  00
 *(.text*)
 .text.Reset_Handler
        0x00005d6c  0x84 ./src/cr_startup_lpc17.o
        0x00005d6c      Reset_Handler
        0x00005d6c      ResetISR
Look at .text section start address. It’s not 0x00004000, but shifted by 0x00004000 from end of privileged_functions section end.
Location counter assignments in linker script such as
/* Non privileged code kept out of the first 16K or flash. */
. = __privileged_functions_start__ + _Privileged_Functions_Region_Size;
doesn’t work as expected.
The same results with Yagarto GNU toolchain (arm-none-eabi-gcc.exe (GCC) 4.6.0).
Although some tutorials doesn’t recommend location counter assignments, GNU ld manual clearly describes this behavior and provides an example usage even.

Hmm. I read again ld manual and found that it’s correct behavior because location counter inside section block is relative. That line must be removed and line
/* Non privileged code kept out of the first 16K or flash. */
. = __privileged_functions_end__;
must be placed at end of privileged_functions block.
And it works as expected both in lpcexpresso and yagarto.

I hurried again :) Final correct line:
/* Non privileged code kept out of the first 16K or flash. */
. = _Privileged_Functions_Region_Size;
Please, do fixes I mentioned. Although demo works fine (only because the LPC1768 flash luckily resides on 0x0, but this demo ported to STM32F2 with flash at 0x8000000 fails), these fixes must be done to get it linked correctly.
