I suspect the recent Bionic changes have broken the install. At least I'm seeing the following:

[Regression Potential] There is regression potential, however with a test rebuild of the main portion of the archive no regressions were found. [Test Case] No regressions in the GCC test suite, and no regressions in the test rebuild of the main component of the archive (all architectures) As a test, a complete archive rebuild (main only) was performed, and no regressions were found with this new package. The archive rebuild also contained updated versions of gcc-7, gcc-8, binutils, python3.6 and python3.7. The GCC and Python packages should not infer with each other. [Validation] Analyze the build logs for regressions. For the cross builds, just make sure that the packages build using the updated sources.
