Apparently this was Surv from package Design.
So the bug is in contributed package Design, and nothing to do with
R-bugs.

Your example is not reproducible without 'library(survival)'.
When I include that, I get

stime status surv
1176 TRUE 176

status <- status=="D"
stime <- death-diag
surv <- Surv(stime, status)
D <- da
