Thanks for the truss output.  I expect that it's this line
in src/create.c:1639

  else if (fstatat (parentfd, name, &st->stat, fstatat_flags) != 0)

Could you please run a debugger like GDB and step through that line
with an offending test case?  My suspicion is that fstatat is incorrectly
reporting that the file size is zero.  If so, can you explain how fstatat
is implemented on your system?  Is the code using the gnulib replacement,
or is fstatat implemented via system's C library, or what?

If you can't run a debugger, simply insert some printf statements
and print st->stat.st_size right after the successful fstatat.
