Octave was not allocating sufficient memory when using the GESDD driver. I've fixed the problem on the stable and development branches. In order to see the fix you will need to build from Mercurial sources or wait until the next release of Octave (3.6.4 or 3.8.0).

I find that Octave crashes when I use the gesdd driver to do svd on complex matrices whose order is larger than 2.

The crash occurred at both stock Octave 3.4.3 on Fedora 16, and my personal build of Octave hg head one month ago (3.7.0+).

Note it goes fine when using gesvd driver.

Below is the code script I use. I'll attach the backtrace output as a file.
