--- Comment #4 from Iain Sandoe <iains at gcc dot gnu.org> --- (In reply to simon from comment #3) > Problem still present in Xcode 4.1beta. >From a GCC perspective, what's needed is: * for someone to file a radar with Apple ("feedback" they are called now) [https://feedbackassistant.apple.com] * If it is acknowledged as an Xcode bug, and we have no way to work around it, then we will just need to document that certain versions of Xcode are not usable. * If the outcome of the FB is that the problem is determined to be with GCC, then we will have to address it. As of now, it's not clear to me that this is a GCC bug - removing a symbol from the library looks like an ABI break.
