Hi, I get a segfault from gb.gsl when running the attached project. I looked at the source and it seems I am allowed to do this... Even if I'm not, a segfault isn't the most charming way to tell me ;-)
GDB output: (gdb) r Starting program: /usr/bin/gbx3 warning: no loadable sections found in added symbol-file system-supplied DSO at 0x7ffff7ffa000 warning: Could not load shared library symbols for linux-vdso.so.1.
