mjog@mjog-dev-box:~/wasmvm$ nm -nC ./envoy-static | grep Envoy::Extensions::HttpFilters::RateLimitFilter::Filter::onDestroy
0000000001b6aad0 T Envoy::Extensions::HttpFilters::RateLimitFilter::Filter::onDestroy()
  • The address of onDestroy(): 0x1b6aad0
  • Runtime Crash addr stack frame #1: 0x5a3e40027cba
  • Address mapping base: 0x5a3e3fa82000
