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". More detail:
