Already tried (correct --apcs-frame to -mapcs-frame in my first mail) 

This is apparently a known problem, saw something about gcc-2.95 not
generating correct stack frames for Arm debugger. A look at the assembly
shows that the generated code is actualy quite different.

But i'm now trying to see if GCC 3 solved the problem (there is a new ARM
back end in Gcc 3 so maybe...) but i've got some difficulties building gcc
3... 

Thanks
