Bugzilla

Also: in terms of the clang-plugin, one spot that I thought would use up big gobs of memory is [this code](https://searchfox.org/mozilla-central/rev/9193635dca8cfdcb68f114306194ffc860456044/build/clang-plugin/mozsearch-plugin/MozsearchIndexer.cpp#534-536) where we read the entire analysis file for a source file into memory, append the new rows, and sort it all before writing it back out. If the analysis file for a source file gets really big this would eat up a lot of memory. I looked at a recent index of m-c to find the largest files in the win64 mozsearch-index.zip file, and got this:

```
$ find . -type f -print0 | xargs -0 wc -c | sort -rn  | head
125440912 ./__GENERATED__/dist/include/mozilla/Assertions.h
 67277607 ./js/src/zydis/Zydis/Generated/InstructionDefinitions.inc
 58214307 ./__GENERATED__/dom/bindings/TestJSImplGenBinding.cpp
 43461257 ./__GENERATED__/dom/bindings/TestCodeGenBinding.cpp
 36553630 ./third_party/sqlite3/src/sqlite3.c
 35245726 ./__GENERATED__/dom/bindings/CSS2PropertiesBinding.cpp
 32859531 ./__GENERATED__/dist/include/nsISupportsImpl.h
 26875546 ./__GENERATED__/dom/bindings/TestExampleGenBinding.cpp
 22401566 ./__GENERATED__/dist/include/mozilla/Likely.h
 19753412 ./__GENERATED__/toolkit/components/telemetry/TelemetryHistogramData.inc
 19729881 ./__GENERATED__/dist/include/mozilla/StaticAnalysisFunctions.h
 19566712 ./toolkit/components/reputationservice/chromium/chrome/common/safe_browsing/csd.pb.h
```

So Assertions.h generates an analysis file 125M big. I don't know how that compares to what else clang is doing and how much memory is available on the system.
