That is not a bug. Without volatile and nothing using the result of the asm,
both the second inline asm and x[0] = 25 store are optimized away (by RTL
DSE1), there is not even anything on the line 14 anymore.
As it is optimized away quite late, the variable x is not optimized away, it
exists, just is completely uninitialized. What you see in the debugger than is
exactly what you would see before the x[0] = 25; store then.
