I once wrote about 64-bit issues and that GiNaC builds fine on Linux/AXP except for shared libraries, where everything segfaulted immediately. Somebody guessed we were suffering from some "static initialization order fiasco". I haven't looked into that since then---which is good, since I just came across this quote from the current GCC caveats list <http://gcc.gnu.org/gcc-2.95/caveats.html>: : Exception handling may not work with shared libraries, particularly on : alphas, hppas, rs6000/powerpc and mips based platforms. Exception : handling is known to work on x86 GNU/Linux platforms with shared : libraries. So, it's not our problem, is it? Doesn't sound good, though. Happy hacking -rbk. -- Richard Kreckel <Richard.Kreckel@Uni-Mainz.DE> <http://wwwthep.physik.uni-mainz.de/~kreckel/>
