--- Comment #8 from Daniel Vollmer <zerolo at gmail dot com> ---
Using g++-7.4.0 I'm now seeing the following:
- Step 1) (the compilation with "-flto -fprofile-generate") still works,
including the visibility warnings mentioned in Comment #2, in particular

- Step 2 now no longer hangs, the Python extensions exits successfully and
seems to generate / write profile data. The code executed to generate the
profiles is multi-threaded.
- Step 3 now fails (during "compilation" of the .cpp files) for at least one
file with the following error:

If I disable threading for the Profile generation (Step 2)), then the
compilation in Step 3) seems to succeed, and I get a functioning result.
