--- Comment #19 from Martin Liška <marxin at gcc dot gnu.org> --- (In reply to Prasannanjaneyulu from comment #18) > Thank you @martin. I am not sure whether ubuntu 16.04 is compatible with gcc > 8.4.0. Our app. is currently built for ubuntu 16.04 and I don't know what > breaking changes it could bring if we upgrade gcc. I strongly recommend to update to a supported GCC. Note that in the meantime we've fixed many issues that can theoretically affect your application. > > Do you know any workaround other than disabling the whole branch coverage? No.
