Is there any code snippet to reproduce it?

The backtrace mentions mongo-perl6-driver…
True, its in the mongodb driver project. The test is in the attachment and it crashed around line 98 or 99. Just finished the 'Find tests' and done the first test of 'Count tests' subtest. These few lines were visible just before the crash; 


...
    ok 10 - Key '_id' does not exist
    ok 11 - Key 'code' does not exist
    ok 12 - Key 'name' exists
    ok 13 - Key 'address' exists
    ok 14 - Key 'city' exists
    1..14
ok 2 - Find tests
    ok 1 - 200 records
... crash ...
The difficulty is that it crashed once but it didn't after repeated tests of the same code.

Attachment: 450-find.t
