URL: https://github.com/llvm/llvm-project/commit/404746b9f21bef631eac09469bfcc35e8cfe0e63 DIFF: https://github.com/llvm/llvm-project/commit/404746b9f21bef631eac09469bfcc35e8cfe0e63.diff LOG: [nsan] Remove mallopt from nsan_interceptors (#101055) Fixes a build failure on 19.1.0-rc1 when building on linux with musl as the libc musl does not provide mallopt, whereas glibc does. mallopt has portability issues with other libc implementations. Just remove the use.
