this is similar to my IDL 5.0 bug i found in idl 4.01 at 23.Dec. 96
which is known to RSI as an internal kernel-Bug of IDL!

i worte a programm that hung the maschine:

pro fail

for te=1,105 do begin
anzahl=te
tname=strarr(anzahl)
for i=0,anzahl-1 do tname(i)='TN_'+strcompress(string(i),/remove_all)

ttyp=strarr(anzahl)
; zum ausuchen / try one of it
ttyp(*)="'String-test'"
ttyp(*)="fltarr(10)"
ttyp(*)="dcomplexarr(102)"

ziel=byte(0)
estring='ziel={'
for i=0,anzahl-1 do begin
if i gt 0 then estring=estring+','
estring=estring+tname(i)+':'+ttyp(i)
endfor
estring=estring+'}'

if execute(estring) then begin
print,' Execute OK: ',te
endif else begin
goto,abbruch
endelse
endfor

abbruch:
print, ' Execute failed at ',te
end

Even worse is the switshing of the data-type every time!
