Have you read the bug report? The problem is obviously related with a
library, namely with libatlas. Try to install libatlas3gf-sse2 3.6.0-24
(if your CPU supports SSE2) to reproduce the problem. However, what
triggers entering this infinite loop - the bug in the library or
something in harminv - this cannot be judged easily, that is why I
reported this bug first to harminv. From the technical point of view it
can be even a problem of the compiler but I think you do not expect me
to report this bug to gcc folks first?

Btw, meep that uses libharminv internally also has the same problem.
