SUMMARY: AddressSanitizer: SEGV /build/glibc-eX1tMB/glibc-2.31/string/../sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S:365
==74==ABORTING
The problem was incorrect initalization of a `TF_TString`. The existing
code initialized it as `new TF_Tstring` (which is not really any kind of
initalization, just memory allocation). `TF_TString`'s have to be
initialized with `TF_TString_Initialize` before they an be used. The
fact that the offending code is using a `unique_ptr` to ensure deletion
of the `TF_TString` makes it all a little clunky.
