[Clas_offline] user_ana now crashes everywhere :-(

[Will Phelps]

Hello Silvia ,

We’re currently having the exact same issue with Ken and Taya. What did you do to resolve this? 

It has been an issue for several months now and we are still working on finding a solution. The SIGFPE error appears to just have appeared one day without any changes to the clas6 environment just like it did in 2013.

We’ve traced it down to this line (line ~625 in fpack.c)
      par[13] = (BIOS_NPHYSREC*BIOS_RECL)/BIOS_NLOGREC;

Where BIOS_NLOGREC = 0 for some reason. Does anyone know what this is? Is anyone using user_ana without problems at the moment?
