It is too small to make sure it is a globally unique identifier. You need 16 bytes (128 bits) minimum. This must be a linker bug. Older lld had a bug where they had a "fast" build-id generator that produced such small (useless) build-ids. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
