Google breakpad give invalid dump info on some devices/cpus/os?

I've compiled and ran google-breakpad on android app successfully, and solved some crashes with the sufficient information collected through it. But among the dumps there're some insufficient ones that give no stack trace or issued models. I spent some time trying to figure out the relationship between dump info and device type but found no traces. Here's my "insufficient" dump, only a memory dump for each thead, no symbols given

And here's what valid dump gives, the crashed thread lists the stack trace
