Geoff, I don't seem to have access to read... <rdar://problem/4428696> a strong symbol in a dylib should not override a weak private extern symbol
Does the radar report describe any workarounds? Does this mean the problem is actually in cctools? Also, the problem doesn't happen with gcc 4.1.1 (but only with 4.2). At this point, I am considering sampling the snapshots for 4.2 and see if I can identify which snapshot caused the breakage in xplor-nih. Jack
