This package has serious 64-bit problems in the original 2.16.1 distribution.
This issue is created on base of a forum post in 2013. Lets take the following minimal observation list:
File: sobs.dat
alpha 20. 0.
beta 16. 3.
gamma 15. 7.
delta 13. 6.
and this configuration file:
File: config.dat
observations
x 2
y 3
transformation
fit v1=0.0, v2=0.0
FIT : y = v1 + v2 * x
The catalog remains empty in this example (but has to be given as dummy). Running this gives a segmentation violation on 64-bit platforms:
