Package: scotch Version: 7.0.0-1exp1 Severity: normal autopkgtest fails for the new scotch v7 package on the MPI tests of dgord and dgpart (check_prog_dgord and check_prog_dgpart rules in src/check/Makefile)

The unreliability of the failure suggests a race condition, likely related to the new dynamic thread management in v7. Perhaps we need a different set of scotch PTHREAD flags when compiling? Review further once v7 has passed the NEW queue to experimental. -- System Information: Debian Release: bookworm/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.15.0-2-amd64 (SMP w/8 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages scotch depends on: ii libc6 2.33-1 ii libscotch-7.0 7.0.0-1exp1 scotch recommends no packages. scotch suggests no packages. -- no debconf information
