Hi! 

  We are working with FFI and we have a few problems with doubles:
  1. In the FFITester, there is a method called testAll. But when I launch 
it, I get "error: problem with doubles".
  2. We have some functions returning doubles like dRandReal() which returns 
a double between 0 and 1. If I call it several times, I get double a few 
times, then I get a "NaN" double (Not a Number) until I quit Squeak and 
restart it.
  3. That's why some functions with doubles as arguments make Squeak crash 
with a segmentation fault. 

  Does anyone know the source of the problem ?
Heeeeeeeelp plz!
Thanks.
Emeric.
