I guess you have tried it with make_release.sh. Had the same issue with it, while building with make_devel.sh worked fine.

manual change this file lib/bls-signatures/contrib/catch/catch.hpp :
static constexpr std::size_t sigStackSize = 32768 >= MINSIGSTKSZ ? 32768 : MINSIGSTKSZ;
to
static constexpr std::size_t sigStackSize = 32768;

This #1002 (comment) worked for me. Thanks :).
