Hi Mohammad.
Thanks for the report. This is a known issue, and is a consequence of how the
`mka' instruction works. The instruction, used to create array values at the
PVM level, requires to stack all the elements of the array in the main data
stack. Jitter stacks are limited, and do not grow, so when the array is big
enough, it leads to this segmentation fault.
This will go away once we change the way `mka' works, which is planned.
