To me, this looks like one old known bug of GCC (of which I'm by no
means certain whether it ever got fixed): calling functions through
function pointers is generally fishy if you're using GNU binutils with
GCC, on PA-Risc.  It's known to fail reliably as soon as you pass a
pointer to a static function to some function in another source file
which then calls it.

In gnuplot, we had to un-static lots of callback functions for exactly
this reason.  The alternative solution, IIRC, was to use HP's binutils
instead.
