I just fixed the problem on the mainline and 7 branch: https://gcc.gnu.org/ml/gcc-patches/2017-06/msg01818.html The testsuite now flawlessly passes at -j32 for me. > Ok, I hope that will help the kernel guys to figure out what the > problem is. libcilkrts does low-level fiddling with the stack pointer and threads, and overlooked the stack bias in 64-bit mode. This resulted in reproducible hangs for some tests of the testsuite and I guess that a high level of parallelism led to a form of congestion somewhere; I'm afraid I can't say more. -- Eric Botcazou -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
