Hm, strange. I don't know why you can't get any debug info, then.

It is indeed very likely the problem is there: typically, problem when
passing complex number at the C/Fortran, this kind of thing.

gcc 3.4 (the one give by open solaris by default), no blas/lapack. I
actually would try this configuration first (no blas/lapack at all), to
be sure it is blas/lapack or us.
