Analyzer openresty-core-dump-analysis

# Name

openresty-core-dump-analysis - OpenResty Core Dump Analysis

This analyzer performs specialized post-mortem analysis of core dump files from OpenResty and Kong applications. It leverages GDB to extract detailed debugging information including C-level and Lua-level stack traces, LuaJIT VM state, nginx module contexts, and memory structures. The analyzer generates comprehensive text reports that correlate native code execution with Lua runtime state, enabling deep troubleshooting of crashes involving the interaction between nginx, LuaJIT, and application code.
