This is quite likely from a libtool-related bug which shows up with 
-m64 on Solaris when using GCC.  The bug causes C++ exception catching 
to not work reliably.  I have attached the patch which was submitted 
to libtool.  This fix will be in the next (soon forthecoming) libtool 
release.

On Solaris, catch code for C++ exceptions is in libgcc_s.  The libc has
default catch code as well, that does an abort.  GCC by default emits on
purpose -lgcc_s -lc -lgcc_s.  libtool's de-duplication magic turns this
into -lc -lgcc_s, which unsurprisingly is the wrong order, since
exceptions will be seen by libc first.  Disable de-duplication for this
reason, such that we can have working C++ libtool built libraries.
