--- Comment #16 from Matthew Krafczyk <krafczyk.matthew at gmail dot com> --- I've just checked this bug again with ubuntu 14.10. This is with glibc 2.19, and with the master branch of gcc (commit 3c4e189973c43b7f3c2ebb27abf32e9cb175ba82). The first fragment succeeds, but the second fragment still fails.
