Well, there's one thing left. The crash that Jack fixed was specific to the case where we get an error from x13as. Why did we get an error? It seems that x13as itself segfaulted when calling the SEATS code. Not exactly a bug in x13as, but due to out-of-date fortran code which gfortran used to work around but not (by default) any more. I'm in the process of replacing the gretl builds of x13as that exhibit this problem with new builds using the gfortran flag "-std=legacy", which reinstates the workaround....
