Maybe if you provide a little more information, we can help.

What kind of "strange character" do you see?
Does your application set CYGSEM_HAL_USE_ROM_MONITOR?  You can tell by
looking for this string in the .../include/pkgconf directory in your
build/install tree.

I tried to follow your suggestion but i can't resolve the problem.
My configuration has been obtain simply from "MICROPLEX Printer Controller
5.0" package "default" option. Now the unique change from default is the
compiler: i'm using the xscale-elf-gcc not arm-elf-gcc.

What are you using "GDB_stub" for?  You've got RedBoot, you don't need GDB
stubs and you don't want/need them in your application.

Good - that's where it's supposed to be.

This says that your application thinks it needs GDB.  Check your 
configuration again.  You should be able to run something like this:
  % ecosconfig new mpc50
  % ecosconfig tree
  % make
  % "make application"
This default setup should create applications which work fine, either loaded
directly by RedBoot and putting the output to the RedBoot console device, or
loaded by GDB and using the GDB protocol for output.

Also, I note by the output above, that your program has failed at PC=0xC894
which is outside of the program, with the stack at 0x01FFFFFC. How did it
get there?  What sort of configuration are you running?

In the ecos configuration tool i set the CYGSEM_HAL_USE_ROM_MONITOR on
GDB_stub. I can find the string CYGSEM_HAL_USE_ROM_MONITOR only in
hal_arm_xscale_mpc50.h file. Reedboot prompt:
