This message is going to stderr. It's not new. In some contexts if
gretl_cholesky_decomp_solve fails there's a fallback, in others not. If
there's a fallback then printing this message is probably redundant; if
not, it might be useful for tracing failure. But maybe it could be
scrapped altogther. If you're getting a ton of these messages it seems
you must be working with a lot of ill-conditioned data!
Actually the really big files happened because of another message,
"cholband <sth> test" or something like that.
Apart from that, I (think I) know what the numerical reason behind all
this is, that's a different matter.
