--- Comment #64 from simon at pushface dot org 2013-01-31 20:48:10 UTC --- I just built Target: x86_64-apple-darwin12 gcc version 4.8.0 20130131 (experimental) [trunk revision 195611] (GCC) and c52104y fails again. Will try removing the call to __gnat_adjust_context_for_raise and report back. Xcode 4.5.2 Darwin 12.2.1
