test failure "the PARI stack overflows"

On a few of my smokers the genprime* tests fail: ... PARI: *** the PARI stack overflows ! current stack size: 4000000 (3.815 Mbytes) [hint] set 'parisizemax' to a non-zero value in your GPRC at t/genprime.t line 24. t/genprime.t .......... Dubious, test returned 255 (wstat 65280, 0xff00) Failed 2/10 subtests PARI: *** the PARI stack overflows ! current stack size: 4000000 (3.815 Mbytes) [hint] set 'parisizemax' to a non-zero value in your GPRC at t/genprime_elgamal.t line 23. t/genprime_elgamal.t .. Dubious, test returned 255 (wstat 65280, 0xff00) Failed 2/10 subtests ... This seems to happen also on some other systems, see http://matrix.cpantesters.org/?dist=Crypt-Primes+0.50 Unfortunately statistical analysis does not give any clues about the possible reasons here.

Fedora usesd to bump the stack for those tests but that doesn't work anymore: https://src.fedoraproject.org/rpms/perl-Crypt-Primes/blob/master/f/Crypt-Primes-0.50-more-stack.patch I've locally dobled again the stack size to ~16Mb in this patch, and now it passes…

Aka it passes on modern Linux (perl-5.30.2, glibc-2.31, gcc-10, kernel-5.6.x) with this patch.
