why does this assembly fail?

Marius Cosa

Hello,

I have this C code

int value_a, value_b ;
value_a = value_b ;

that translates to this assembly:

0x0002B128  E58D600C  STR       R6,[R13,#0x000C]

but the assignment fails - both variables are allocated on the stack. if I allocate the target variable in RAM (say, using "static") it works. alignment issue? something?
