Can you please test it with a new release of GCC? If yes, then please attach the pre-processed file and regex.gcda file that's needed for -fprofile-use.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64636 --- Comment #2 from Carson Gaspar carson at taltos dot org --- Removing -fprofile-use also makes the compilation work, so it appears to be a problem with profile feedback combined with LTO. Either works individually, but error out if used together.
