Для работы pthread_cancel требуется libgcc_s. Такой зависимости у glibc-core нет. Многопоточное приложение, которое пересобрано с новой glibc, зависит только от libc.so.6 (чтобы убедиться в этом, можно собрать приложенный src.rpm -- это тестовая программа из man pthread_cancel). Приложения, использующие pthread_cancel, _пока что_ работают по счастливой случайности - пакеты, которые пока не пересобраны с новой glibc, зависят от (пустышки) libpthread.so.0 из пакета glibc-pthread. А у пакета glibc-pthread есть зависимость от libgcc_s. Нужно добавить к libc-core зависимость от libgcc_s. 230614 1 iv 2023-07-31 13:25:54 +0300 Для воспроизведения проблемы в Сизифе сейчас достаточно пересобрать libdb4.7. hsh libdb4.7-4.7.25-alt12.src.rpm hsh pthread_cancel_sample-0.0.1-alt1.src.rpm hsh --init --pkg-build-list 'pthread_cancel_sample' В полученное окружение libgcc1 не попадает. $ hsh-shell [...] -bash-4.4$ pthread_cancel_sample libgcc_s.so.1 must be installed for pthread_cancel to work Aborted -bash-4.4$ 230623 2 asheplyakov 2023-07-31 14:45:07 +0300 #326131 TESTED #1 [test-only] sisyphus glibc.git=2.37.0.22.3593050c27-alt2 231693 3 repository-robot 2023-08-20 09:00:05 +0300 glibc-6:2.38.0.6.g7ac405a74c-alt1 -> sisyphus: Sat Aug 19 2023 Gleb F-Malinovskiy <glebfm@altlinux> 6:2.38.0.6.g7ac405a74c-alt1 -
