Perhaps.  I can't reproduce the problem with Octave 2.1.64 on a Debian
system, which currently has

devzero:1850> dpkg -l libc6
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed

ii  libc6          2.3.2.ds1-18   GNU C Library: Shared libraries and Timezone

In any case, I don't think it is really a bug in Octave.

What happens if you try a simple C++ program to test sqrt(NaN+NaN*i)?
