I can't close this, but it turns out this also happens on newer versions of debian like stretch (with perl 5.24). I had tried stable but that only has 5.20, so it seems this may be new in the 5.22ish area. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to perl in Ubuntu. https://bugs.launchpad.net/bugs/1668450 Title: perl_clone of libperl causes segfault on xenial, yakkety, zesty ok on trusty Status in perl package in Ubuntu: New Bug description: For using perl in C++ programs unfortunately a simple call to perl_clone causes a segfault.
