These runs are from 3.7 release branch and not all the test framework
improvements have been backported there.
I have a patch [1] which backports every change under tests/ dir but it is
failing because some of the required code changes have not been backported.

For this particular crash that you are observing, the test which generates
the core is ./tests/basic/tier/tier-file-create.t. How to determine? Well,
based on core name which has PID and then look into messages or logs to see
what was happening during that time.

The cause of the crash has been documented well in the bug [2] and a
partial fix [3] by Pranith is available.

Pranith,
With respect to dict_foreach problem you mention, won't taking a lock in
dict_foreach solve the problem?
