Congratulations on your excellent analysis. Well, the fix has been applied to CVS already: <http://down.physik.uni-mainz.de/cgi-bin/viewcvs.cgi/GiNaC/ginac/function.pl.diff?r1=1.86&r2=1.86.2.1&cvsroot=ThEP>
I'm beginning to have doubts whether this is the proper fix, because:

It may happen that the construtor of function_options() is called before the call of library_init(). function_options() is called during registration of class container by statement GINAC_DECLARE_REGISTERED_CLASS(container, basic) in file container.h (line 130).
Isn't library_init() supposed to solve all problems of this kind by being the first static object to appear in any compilation unit? library_init() is declared in ex.h which is the first file included from container.h, so it can't come from there. And the GiNaC class registry doesn't use function_options, so I don't understand why the declaration of container<> would create a function_options object. The only compilation units creating function_options are the various inifcns*.cpp files which include inifcns.h -> function.h -> exprseq.h -> container.h -> ex.h and should see library_init() before any function_options.
