It has segfaulted. Now if you want to make any progress, you'd have to
run it under gdb to find where and why.
For this, you need a debuggable executable.

Edit the Makefile in your Sophie source tree manually
to compile it with '-g', no optimization and not stripping the
executable file. If you don't know how to do this, post the two
lines of your Makefiles setting CFLAGS and LDFLAGS.
I don't have a Solaris box at hand to test (much less 2.6!)

If you can generate a debug executable, run it under gdb:

$ gdb ./sophie
(gdb) run -d

When Sophie segfaults, you will be thrown to the gdb prompt again.
Here, type:

(gdb) bt

and post the output.

Of course, if the segfault occurs in libsavi itself, which I fear, it
won't tell us much...
