What does swapinfo say?
Run top (1sec) or 'systat -vm 1' and see if that gives some indication.

This is to warn against -O3 or -O0 (no opt).  -Os is a collection of
optimizations that is between -O1 and -O2.  That is -Os includes
everything that -O1 does, and -O2 includes everything that -Os does.
In otherwords:  -O1 < -Os < -O2   (properly)

The reporter is having trouble with both -O2 and -Os, so that should not
happen.
