Comparing _mongoc_cursor_run_command()'s call to bson_reader_new_from_data() with other instances through libmongoc, I noticed that it doesn't check and free a previously allocated reader. I believe this is related to the following memory leaked spotted in several PHPC test failures:
==10816== 160 bytes in 1 blocks are definitely lost in loss record 38 of 94 ==10816== at 0x4C2BBA0: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==10816== by 0x911A2F: _emalloc (zend_alloc.c:2427) ==10816== by 0x911D91: _safe_emalloc (zend_alloc.c:2583) ==10816== by 0x911EE4: _ecalloc (zend_alloc.c:2610) ==10816== by 0x96F98F4: php_phongo_calloc (php_phongo.c:2030) ==10816== by 0x96A4E4D: bson_malloc0 (bson-memory.c:103) ==10816== by 0x96A654C: bson_reader_new_from_data (bson-reader.c:541) ==10816== by 0x96C0898: _mongoc_cursor_run_command (mongoc-cursor.c:559) ==10816== by 0x96C3A1D: _mongoc_cursor_cursorid_refresh_from_command (mongoc-cursor-cursorid.c:72) ==10816== by 0x96C3E1A: _mongoc_cursor_cursorid_prime (mongoc-cursor-cursorid.c:136) ==10816== by 0x96C4259: _mongoc_cursor_cursorid_next (mongoc-cursor-cursorid.c:224) ==10816== by 0x96C1323: _mongoc_cursor_find_command (mongoc-cursor.c:775)
