Racily dirty?  Or just being stat-dirty is sufficient to cause the
"stash create" to fail?

I think, from the above reproduction recipe, that the breakage does
not depend on racily-clean index entries (i.e. file touched within
the same timestamp as the last write of the index without changing
their size).  So s/racy-dirty/stat-dirty/ (both on the title and the
body) would be a sufficient fix.

Thanks.
