Backtrace stopped: previous frame identical to this frame (corrupt stack?)
It seems others had this problem on archlinux, too.
Well, there are 2 issues I can guess from here:
1) armv5 devices don't have neon, so the plugin really doesn't need to be
built in the first place, though it shouldn't hurt
2) not all armv7 devices have neon either, so the plugin definitely should catch a
SIGILL or properly probe if neon is available
Probing neon is fairly trivial. IIRC it's passed in as part of auxv. Maybe the module
is really just missing a check? Or it compiles its own check with neon already, which
would be a serious bummer :).
