The second test case is valid, but processor dependent according to e.g. Fortran 2003: 13.7.121 TRANSFER (SOURCE, MOLD [, SIZE]) Result Value. [...] If the physical representation of the result is longer than that of SOURCE, the physical representation of the leading part is that of SOURCE and the remainder is processor dependent. Examples: PGI, flang 1.5 give: % ./a.out | cat -ve '^@ ' 6$ sunf95, g95: '^@^@^@^@^@^@' 6$
