This has finally been fixed upstream, please pull the following patch to fix this issue: https://github.com/abseil/abseil-cpp/commit/7335a36d0b5c1c597566f9aa3f458a5b6817c3b4 In addition it is not necessary anymore to run the testsuite with --no-parallel, the problem was linked to the use of the rdcycle instruction which jumps when the process is rescheduled on another CPU. I have tested the following patch with the above upstream commit: diff -Nru abseil-20230802.1/debian/rules abseil-20230802.1/debian/rules --- abseil-20230802.1/debian/rules 2023-09-07 19:11:48.000000000 +0200 +++ abseil-20230802.1/debian/rules 2024-03-23 16:56:20.000000000 +0100 @@ -28,12 +28,6 @@ ABSL_RUN_TESTS=ON endif -# Debian's RISC-V builders don't have enough resources to run tests in parallel. -# See https://bugs.debian.org/1025221. -ifneq ($(filter $(DEB_HOST_ARCH),riscv64),) -ABSL_TEST_EXTRA_ARGS=--no-parallel -endif - %: dh $@ Regards Aurelien -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://aurel32.net
