I see, thanks for the explanation.

How about his patch? It does not add a file, though it does add an
external function which requires a rename in libsanitizer/libbacktrace
(I don't know whether that requires changes in any other places).

[ Also, it inlines backtrace-vector.c into alloc.c and mmap.c, so it
duplicates code. If that is not acceptable, I could move it to
internal.h as static inline or static ATTRIBUTE_UNUSED. ]

Thanks,
