Ludovic answered this nicely.

This shows lots of symbols being resolved, nothing helpful.

That is there, although there are more symbols looked up after it.

Ludovic answered this nicely.

Ludovic also suggested removing '-fstack-check' from the list of
compiler options. I did that, rebuilt the static and dynamic
libraries, and the bug went away; the test code works with both static
and dynamic libraries.

So I will leave hppa in the arch list, but remove the stack check
