My multithreaded code didn't work and I thought
may be gcc is making a wrong optimization.
Turns out to be my own fault.

But still, I'm curious, can gcc make a wrong
optimization not knowing that a variable may
be changed by another thread?

I notice that both glib and vala use volatile ref_count.
So, if we were to do our own application-specific
memory management, shouldn't we have volatile
somewhere?


Nice day
