From 0024172d909ec73a9ce9ffdfc9fdd4382080e110 Mon Sep 17 00:00:00 2001 From: Andrew Fish Date: Mon, 7 Aug 2017 11:26:05 +0800 Subject: [PATCH] BaseTools: Fix Segmentation fault: 11 when build AppPkg with XCODE5 it is a bug in mtoc setting the size of the debug directory entry to the size of the .debug section, not the size of the EFI_IMAGE_DEBUG_DIRECTORY_ENTRY. It was causing a loop to iterate and get bogus EFI_IMAGE_DEBUG_DIRECTORY_ENTRY data and pass that to memset() and boom.
