• gcc 16.1: ICE when an importer compares a module type whose operator== is a defaulted friend

• Shared images are DF_STATIC_TLS on GCC (static libstdc++'s call_once uses initial-exec TLS): dlopen fails once dependencies hold more than a few KB of TLS

• fix: emit sbom states the lock's spelling of a package, so one package has several purls

  mcpp-community/mcpp#892 · opened on Nov 6, 2026

• fix: emit sbom and --locked read a missing mcpp.lock as an empty one, so neither says it is missing
