IAR Embedded Workbench Release Problem

Hi,

I wrote a program which ran in Debug Mode without problems. Here I used 
the compact emulator M3962PT3-CPE. But when I tried to release it to the 
M16C62P Microcontroller via Hexload it didn't work. Now I found out, 
that the following declaration doesn't work in Release Mode:

[c]unsigned char *pointer = "Text";[\c]

Here the pointer doesn't get a certain value. But when I write it like 
this:

[c]Unsigned char *pointer;
pointer = "Text";[\c]

everything works fine and there are no problems.
I allready compared the .lst-Files from the via Debug and Release 
compiled files and there is no difference. Does anybody have an 
explanation for that? Thank you very much!!!
