Problem look similar to #1748 in this case on instance of com.soywiz.korag.AGNative. When walking over fields of AGNative instance field 16th, onReady we get

(lldb) p (void*)Konan_DebugGetFieldAddress(0x101a51738, 16)
(void *) $42 = 0x0000000101a517c8
(lldb) p (char*)Konan_DebugGetFieldName(0x101a51738, 16)
(char *) $43 = 0x00000001003cc641 "onReady"
(lldb) x/2g 0x0000000101a517c8
0x101a517c8: 0x3ff0000000000000 0x0000000101a51908

Looks like some other module wrote 0x3ff == 1023 on place, where onReady callback is expected. This likely happens due to fact that we see mismatching object layout in different libraries.

Fixed in master.
