Ok I looked at cutter.c again and now I think I found the cause:
Linux must default to bigger thread stacks than FreeBSD, FreeBSD's
default seems to be 2 MB on amd64 and MAXFRAMESIZE is almost 1 MB...
Try the patch below, you can put it in files/patch-z-cutter.c
in the port dir. (the thread.c part is FreeBSD port specific, it
caused a different crash with --edit.)
HTH, :)
