It seems to be a bug.  Please file it on issuetracker, I'll try to fix it as
soon as possible.   Quite likely, it's just not implemented, in which a quick
workaround is to use romberg:

(6) -> romberg(x+->exp(-x^2),0,1,0.1,0.1,10,100)

   (6)
   [value= 0.7468241328 1242702543, error= 0.4 E -19, totalpts= 2049,
    success= true]
   Type: Record(value: Float,error: Float,totalpts: Integer,success: Boolean)
