Ok, I'm making progress now. I noticed in the thread that Alan referred me to that someone had worked around the problem by disabling compiler optimisation. That worked for me too, although in fact all I needed to do was disable inline functions, ie:
-O3 -fno-inline-functions This worked for 2.0.0 and 2.1.1-unstable. So now I have to decide which version to test with. I'm interested in measuring performance and trying out some of the plug-in interfaces to see if trafficserver might be suitable for my application. Which version do you recommend? How unstable is 2.1.1?
