--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
The compiler segfaulted.
Note that GCC 5.4 is no longer maintained, esp. for using link-time
optimization you should try newer toolchains using GCC 7 or GCC 8.
In any case to debug your issue you need to follow
https://gcc.gnu.org/bugs.html
and provide a testcase in the form of preprocessed sources.
