Thank you for your kind words. The updates do not appear to be aggressive enough for Travis CI and it is now a calibration task. I am restricting the CPU in Docker to 1.5 to see if I can isolate it locally. My advice would be to use Eclipse because it supports pretty much every language. I am not going to install Eclipse and go through the process of configuring everything. * Configure the build with the `-g` debug flag in `config/configure.ac`. * Launch the `heron-dev` docker container. * `docker ps` and then `docker exec -it` to open a second terminal into the `heron-dev`. * Install `gdb` attach and set your breakpoint `-b` and watchpoints in your tests. * Run the `stmg_unittest` in isolation. * Good bug hunting. **_EDIT:_** I do not like referencing Stackoverflow but [this too](https://stackoverflow.com/questions/45812725/c-debugging-with-gdb-bazel-emacs). <details><summary>Docker 1.5 CPU build and test</summary> ```bash INFO: Elapsed time: 3726.921s, Critical Path: 514.36s INFO: 5243 processes: 2403 internal, 2840 local.
