(In reply to Michael 'veremitz' Everitt from comment #9) > See also https://reviews.llvm.org/D63785 . Using patch from https://reviews.llvm.org/D63785#1921014 and replacing all instances of 'SANITIZER_GNU' with 'defined(__GLIBC__)' seems to work here. (In reply to Jory A. Pratt from comment #8) > Simple solution is use.mask > > sys-libs/compiler-rt-sanitizers -libfuzzer -sanitize -xray This should actually be 'package.use.mask' for that syntax, and using: sys-libs/compiler-rt-sanitizers -sanitize seems to be adequate so far .. unless I run into later difficulties...
(In reply to Michael 'veremitz' Everitt from comment #10) > > sys-libs/compiler-rt-sanitizers -sanitize > > seems to be adequate so far .. unless I run into later difficulties... should actually be 'sanitize' without the minus, as its masking, not Un-masking! Added https://reviews.llvm.org/D63785#2323359 to upstream bug.
