I imagine that, after enabling SSE2 in Fedora 29, we are compiling a
different code path
that fails. I don't have any experience with this kind of code.
The error is related with _m_from_int64, that seems undefined? But
_m_from_int64 is defined in one of the *intrin.h headers. I'm don't know
what is happening.
In /usr/lib/gcc/i686-redhat-linux/8/include/mmintrin.h,
_m_from_int64 is defined under a '#ifdef __x86_64__' guard. Thus, it's
not defined on i386.
