Note: If you build cupsd on Solaris SPARC as default it seems to compile
with the flags for 32 bit, to get 64bit with gcc you must set '-m64';

Here is the runtime link list (ldd output) with some remark numbers on the
right hand side:

# /usr/local/sisis-pap/cups2/etc/cups/init.d/cups start

        /platform/SUNW,SPARC-Enterprise/lib/sparcv9/libc_psr.so.1

(1) libz.so and libiconv.so.2 are heavily used in our 64bit system and I
think they are fine (and not even involved in the moment of crash)

(2) they come from gcc-4.9.2

I will see if I have the time to mail it down;
