--- Comment #5 from seurer at gcc dot gnu.org --- make -k check RUNTESTFLAGS="conformance.exp=26_numerics/random/random_device/cons/token.cc" This is from powerpc64le-unknown-linux-gnu/libstdc++-v3/testsuite/libstdc++.log Setting LD_LIBRARY_PATH to :/home/seurer/gcc/git/build/gcc-test/gcc:/home/seurer/gcc/git/build/gcc-test/powerpc64le-unknown-linux-gnu/./libstdc++-v3/../libatomic/.libs:/home/seurer/gcc/git/build/gcc-test/powerpc64le-unknown-linux-gnu/./libstdc++-v3/../libgomp/.libs:/home/seurer/gcc/git/build/gcc-test/powerpc64le-unknown-linux-gnu/./libstdc++-v3/src/.libs::/home/seurer/gcc/git/build/gcc-test/gcc:/home/seurer/gcc/git/build/gcc-test/powerpc64le-unknown-linux-gnu/./libstdc++-v3/../libatomic/.libs:/home/seurer/gcc/git/build/gcc-test/powerpc64le-unknown-linux-gnu/./libstdc++-v3/../libgomp/.libs:/home/seurer/gcc/git/build/gcc-test/powerpc64le-unknown-linux-gnu/./libstdc++-v3/src/.libs:/home/seurer/gcc/git/build/gcc-test/./gmp/.libs:/home/seurer/gcc/git/build/gcc-test/./prev-gmp/.libs:/home/seurer/gcc/git/build/gcc-test/./mpfr/src/.libs:/home/seurer/gcc/git/build/gcc-test/./prev-mpfr/src/.libs:/home/seurer/gcc/git/build/gcc-test/./mpc/src/.libs:/home/seurer/gcc/git/build/gcc-test/./prev-mpc/src/.libs:/home/seurer/gcc/git/build/gcc-test/./isl/.libs:/home/seurer/gcc/git/build/gcc-test/./prev-isl/.libs Execution timeout is: 300 spawn [open ...]^M terminate called without an active exception FAIL: 26_numerics/random/random_device/cons/token.cc execution test I assume the LD_LIBRARY_PATH there is the one used and nothing in it appears out of order. BTW, I tried various changes in configure options, build compilers, binutils, and such in case something there was an issue but it always fails on just this one power 8 system. It works fine on another similar power 8 and other power X (X!=8) systems.
