Hi everyone,
Following some problems I experienced with Network.HTTP.Client.TLS, I found out the problem was specific to bytestring library version 0.10.2.0 and most likely fixed with this commit https://github.com/haskell/bytestring/commit/86df1f17b2332940df69f484182c5c2... .
The default version shipped with GHC 7.6.3 (0.10.0.2) works fine, and the version after 0.10.2.0 (that is, version 0.10.4.0) also works.
It was suggested that I mention on here that I think we should deprecate the 0.10.2.0 version of bytestring specifically, since that is the one that introduces the problem, and there can be problems with having to specify specific versions of bytestring as a dependency when compiling across GHC versions.
