[Gretl-devel] Re: error with sudden "magic" appearance of complex values

Hi, with the March 7th snapshot (on Windows) I'm getting a weird error saying that the invpd() function doesn't support complex arguments. Fair enough, but this code has never used complex numbers. Debugging shows that a certain input matrix indeed is printed by gretl as a complex matrix of zeros: Pmat (2 x 2)  0.00000 - 0.00000i   0.00000 - 0.00000i  0.00000 - 0.00000i   0.00000 - 0.00000i But again, I'm not working with complex numbers here. This matrix should be real, and I'm not using any of the new gretl functions for complex numbers. Could this be some kind of underflow problem where suddenly gretl interprets stuff as complex?
