Hi, this is what valgrind shows
==23137== Invalid read of size 2

==23137== Address 0x62f3430 is 224 bytes inside a block of size 248 free'd

that is that in sh_eval_20120720() witin the while loop the stream is
freed by sh_exec() -> unall() -> _nv_unset() -> sfclose()
and later on after the loop with sh_freeup() -> sh_funstaks() -> stkclose()
