A segfault in a perl script indicates an error in the perl
interpreter, or that you are running out of memory. Another
possibility may be that you are overwriting the perl script that is
currently executing -- I don't know what happens in this case, but I
think nothing should happen since the perl interpreter reads the
script file in the beginning and then ignores all changes.

Do you have another perl version with which you can try?

Since you mention that you run in parallel, maybe there is another
resource (not memory) that is exhausted, such as threads or processes
or stack space. Maybe using fewer workers would change things?
