In Issue 891026 I reported a pathologically slow compile of src/third_party/angle/src/libANGLE/renderer/gl/DispatchTableGL_autogen.cpp on macOS with ASAN turned on and symbol_level=1. Removing symbol_level=1 allows the compile to proceed.

Attached is the preprocessed file, generated with this command line (extracted from Goma and modified):

I've confirmed locally that attempting to compile this file with the following command line reproduces the pathologically slow build.
