I don't see an inconsistency in my answers. If you mark local variables as
having a reference to the stack pointer before combine, then you should handle
log_links as appropriate.
I am explicitly not telling you what to do.
When I use static inline attribute without any optimization as follows, stack
space is stacked. As a result, a stack overflow is caused. This problem came
from using gcc-4.2.0 for linux kernel which uses many inlines.
