Reproduce the listed code_api|tool.drcachesim tests in the bin32 debug build, starting with the missfile command and suite/tests/bin/simple_app. Compare the failing exit-code-11 runs across the drcachesim cases and inspect the available failure output or dump-core settings. Done means the affected 32-bit debug tests complete successfully.
