"Segmentation fault (core dumped)" on Stage 3

[zmy24]

I encountered an error "Segmentation fault (core dumped)" while running stage3.
Then, I set "ulimit -c unlimited', and still encounter the same error:
Core was generated by `fs all_sample_impute.cp -hpc 0 -allowdep 0 -makes3 -dos3 -combines3 -allowdep 1'.
Program terminated with signal 11, Segmentation fault.

Furthermore, I would like to ask if it is possible to resume running from where the previous error occurred, as restarting would be quite time-consuming.
