Looks very similar to bug#51864, but that one was fixed a day before your binary was built. So I'm not sure what's going on. However, it sounds like it's exactly that bug, because after the fix default_face cannot be a NULL pointer, according to my reading of the code: default_face = FACE_FROM_ID_OR_NULL (f, face_id); if (!default_face) <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< default_face = FACE_FROM_ID (f, lookup_basic_face (w, f, DEFAULT_FACE_ID)); } /* Optimize common cases where we can use the default face. */ if (noverlays == 0 && NILP (prop)) { SAFE_FREE (); return default_face->id; } /* Begin with attributes from the default face. */ memcpy (attrs, default_face->lface, sizeof(attrs)); It seems to crash in the call to memcpy. Or maybe the backtrace is inaccurate, this being an optimized build. ^ permalink raw reply [flat|nested] 5+ messages in thread
