Anew octave2.1_2.1.48 with debugging symbols is in ~edd on paer, could someone please install it? I can't convince octave to ignore its rpath so its looking at the non-debug version in /usr/lib/octave-2.1.48. Or else if there is a gdb trick, I'd take that too. LD_LIBRARY_PATH=... gdb fails as well. Dirk -- Don't drink and derive. Alcohol and algebra don't mix.
