Hi,
Really often application core dumped, when sending mongodb query with some
mongoc driver writing function like insert or update, or even when
iterating cursor returned frome the mongoc driver. Moreover, it may
complete with no issues with the absolutely identical queries.
Following the gdb trace (may be question is not so correct, but) is it
possible to identify which side the issue on systems or driver? It seems
that the issue somewhere between mongoc makes strlen call.
Sorry, if i missed something.
