Test case failures on rhel 7.6 ppc64le platform

Hi All,

I had build the nginx binary on rhel 7.6 ppc64le (version 1.17.1.1rc0) from source code - https://github.com/openresty/openresty.
Please note that, I had copied and used ppc64le compiled LuaJIT code while building openresty (nginx).
Below command I used to compile the openresty -

./configure --with-cc-opt="-DNGX_LUA_USE_ASSERT -DNGX_LUA_ABORT_AT_PANIC" --with-http_image_filter_module --with-http_dav_module --with-http_auth_request_module --with-poll_module --with-stream --with-stream_ssl_module --with-stream_ssl_preread_module --with-http_ssl_module --with-http_iconv_module --with-http_drizzle_module --with-http_postgres_module --with-http_addition_module --add-module=/usr/openresty/openresty_test_modules/nginx-eval-module --add-module=/usr/openresty/openresty_test_modules/replace-filter-nginx-module

And then tried to execute the test cases for 'resty-cli' like below -

[root]# pwd
/usr/openresty/openresty/openresty-1.17.1.1rc0/build/resty-cli-0.25rc2
[root]# prove -r t

NOTE: The 'resty-cli-0.25rc2' version is 0.25 which was downloaded as part of openresty bundle.

I am getting below test case failures -

Please help suggest if I need to export any specific environment/setup any additional service or should try any compiler flag/somehow increase timeout value to make these test cases pass?

Start by reproducing the failures with prove -r t in the resty-cli-0.25rc2 directory on RHEL 7.6 ppc64le. Focus on t/resty/options.t and the assertions in t/lib/Test/Resty.pm, comparing the --shdict and debugger output with the expected results. Done means identifying the platform-specific cause and providing a verified resolution or a documented limitation.
