I am running gretl 1.9.5 on Ubuntu 11.10. Here is a simple code to replicate the issue:
nulldata 500 function bundle pippo(scalar n) bundle pluto matrix x = I(n) pluto["mymat"] = x return pluto end function bundle pluto = pippo(3) bundle pluto = pippo(4) Click on the bundle from the "session icon view". Gretl quits with a segmentation fault error. See you Giuseppe
