I tried the suggestion and was granted a SEGV ;(
Does this look correct to you?
bt=nv_search("_Bool",shp->bltin_tree,0);
np = nv_open(shp->var_tree,...);
nv_settype(np, bt, 0);
The code gives me this SEGV:
(gdb) where
#0 0x0000000000803200 in sh ()
#1 0x0000000000495e91 in clone_all_disc (np=0x7ffff7ee2700,
