Actually, the test code you posted runs as follows:
No optimization:
bee7ee743fffffff
3fffffff00000001
-O, -O2, -O3:
3fffffff
3fffffff00000001
If I add the line
*result = 0LL;
before the inline assembly, then the output is like in my previous post.
Based on the result of the no-optimization run, it definitely looks like an
alignment problem. Maybe with the other optimization flags the memory space
just above is set to 0.
