invfreqs is a fairly sophisticated math routine.  I seem to recall recently someone having problems with 3.6.3 math library, updating and then having no problems.  Try 3.6.4 instead if you can remember the commands you used.

Are you able to compile a debug version of Octave and attempt to reproduce the problem with it or run this version under valgrind?

There is barely any information here to diagnose the problem. The stack trace isn't informative; just looks like unpredictable memory corruption. At the very least, can you tell us which commands you were actually running?

I ran Octave 3.6.3 on Fedora 17 doing some lightweight poking around (typed 24 commands on the command line, mostly simple tests and calculations: function defs, 'type fun', calling once freqs and invfreqs, this type of things). I then exited by typing Ctrl-D. Octave crashed, complaining about corrupted memory allocator. I enclose the resulting stack printout.

This is for information mostly---I was able to reproduce this crash once by cutting and pasting commands from the history list, but other times it ran just fine. Perhaps someone can glean something significant from the stack trace while debugging another problem.
