I am really suspicious that this means your libperl was built in an unsafe
fashion, that is, by injecting configuration choices as random -D switches
in the build process rather than making sure the choices were recorded in
perl's config.h. As an example, looking at the perl 5.24.1 headers on
a Fedora box, it looks to me like PERL_SAWAMPERSAND could only get defined
if PERL_COPY_ON_WRITE were not defined, and the only way that that can
happen is if PERL_NO_COW is defined, and there are no references to the
latter anyplace except in this particular #if defined test in perl.h.

Where did your perl installation come from, anyway? Are you sure the .h
files match up with the executables?
