Hi, I tried the sample code, and it worked well:
(sid_mipsel-dchroot)jpuydt@eller:~$ ./hypergeom hypergeom(5.500000e+00, 2.279935e+00)=8.363951e-07 (sid_mipsel-dchroot)jpuydt@eller:~$ ./hypergeom 0.6 0.5 hypergeom(6.000000e-01, 5.000000e-01)=9.166128e-01 (sid_mipsel-dchroot)jpuydt@eller:~$ ./hypergeom 0.5 0.6 hypergeom(5.000000e-01, 6.000000e-01)=9.462169e-01 I'm using a chroot on a mipsel box with flint 2.5.2-21 and flint-arb 1:2.17.0-1. Upstream had the same experience, and ran the sample in valgrind without seeing anything wrong. Can you tell us more? JP
