Hi Dave I found a problem that crash built for ARM64 and running on an X86_64 cannot load extensions as the type for the shared object is not accepted. There is a fix for this for ARM running on X86 that has to be introduced in case as well. Function is_shared_object in file symbol.c case EM_X86_64: if (machine_type("X86_64")) return TRUE; break; should be changed to case EM_X86_64: if (machine_type("X86_64") || machine_type("ARM64")) return TRUE; break; Jan Jan Karlsson Senior Software Engineer System Assurance Sony Mobile Communications Tel: +46 703 062 174 jan.karlsson@sonymobile.com<mailto:Firstname.Lastname@sonymobile.com> sonymobile.com<http://sonymobile.com/> [cid:image001.gif@01CF809F.81560F50]
