# Is this a bug in NIntegrate?

Fixed in 10.1

Bug is present as of version 10.0.2 checked on windows 7, 64 bit

Is this a bug or I missed something? NIntegrate seems to give a different answer for the same integrand when the option Method -> {Automatic, "SymbolicProcessing" -> 0} is given.

$Version (* "10.0 for Mac OS X x86 (64-bit) (June 29, 2014)" *)$Assumptions = w ∈ Reals;
FEx[w_] = (I E^(-25 + 5 I w - w^2/4) Sinh[5 w])/Sqrt[2];
NIntegrate[Conjugate[FEx[w]]*FEx[w], {w, -∞, ∞}]
NIntegrate[Conjugate[FEx[w]]*FEx[w], {w, -∞, ∞},
Method -> {Automatic, "SymbolicProcessing" -> 0}]
(* 0.313329 + 0. I *)
(* 0.626657 + 0. I *)


version 10

version 9

version 8

It seems to have worked in version 7.
