We are getting what might be a similar crash (also EXC_BAD_ACCESS), though it's not in sharedRunLoop and the stack trace doesn't have any detail. It seems to only happen where we have Location permissions set to "Always" (set and used with a different LocationManager outside of MapBox) which is only a subset of our users. It does not always happen, we haven't been able to nail down exact circumstances, other than the app is backgrounded. The exception looks like:

com.mapbox.common.Unspecified Worker 1 (37): EXC_BAD_ACCESS (code=10, address=0x123ef4000)

The stack trace is just:
#0 0x00000001047b3f2c in ___lldb_unnamed_symbol2102 ()
#12 0x0000000224c500ec in _pthread_start ()
