I am encountering nondeterministic hangs of PARI/GP while running its testsuite on macOS. It seems to happen in particular in higher CPU load situations. The hang appears to be a pthread deadlock. In both of the tests that I have seen affected by it (bnf, ellrank), the backtrace shows "ZM_gauss", via "gen_inccrt_i".
