Issue #11109 has been updated by Jeffrey Yang.


I double-checked the backtrace in the attached log, in which it shows the rb_integer_from_bson_int64 causes the crash, however I was not sure. Could you guys still check the attached log file for confirmation?

Of course, I will contact the author of BSON and show him the log.

Apologizes if it's a wrong bug.
