Got CatastrophicError in com.semmle.inmemory.trap.TrapScanner

While compiling [chromium](https://www.chromium.org/Home) with CodeQL, I meet lots of CatastrophicError.

I build the chromium without CodeQL first, then I delete some compiled objects and recompile them with CodeQL.

The error log contains the error message in chromium but the chromium build process seems successful even with these error logs.

Start by reproducing the Chromium compilation with CodeQL and inspect the reported stack frames in TrapScanner.java and TRAPReader.java. Compare the malformed or truncated .trap inputs with the EOF handling at those entry points; done means the cause is identified and the reported CatastrophicError is prevented or handled correctly.
