Potential segmentation fault in semmle_utils.cpp Logger / bazel?

Description of the issue In the last few days I've started getting intermittent (say 10%) SIGSEGV crashes during dotnet restore and dotnet build when running under CodeQL via GitHub Actions Runner.

I've managed to capture a core dump and ran gdb backtrace on the offending thread from a GitHub Action Runner.

I notice in the stack trace context line 3 it mentions Logger::Logger in semmle_utils.cpp just before entering bazel_runner.

I don't have a separate test case, but I can re-run the build and every now and then it will trigger with a failure; without CodeQL there is no issue.
