Use the following command to reproduce the problem

curl -vkl http://127.0.0.1/

Reproduce the crash with the supplied nginx.conf on mips64 using curl -vkl http://127.0.0.1/, then inspect the core dump and debug logs. The report names no source file or test; done means identifying the failing path and verifying that the segmentation fault no longer occurs.
