This code will seg-fault if I start instr1 after instr2. I would have
assumed this is legal? The backtrace is given below.


chn_S "testChan", 3

instr 1
k1 metro 1
krand randh 10, 1
if k1 ==1 then
   Sname sprintfk "chane%d", krand
   chnset Sname, "testChan"
endif
endin

instr 2
Sname chnget "testChan"
endin


Program received signal SIGSEGV, Segmentation fault.
