Haven:write_sav() will produce invalid SPSS files under some circumstances. Here's an example that won't work with SPSS v23. It seems an issue with string that are exactly 255 characters long.

df = data.frame(row.names = c("1","2"))
df$A = 1
df$B = ""
df["2","B"] = "123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789|123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789|1234567890123456789012345678901234567890123456789|12345"
