--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> 2012-12-07 21:13:57 UTC --- Created attachment 28898 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28898 Test case (still depends on the iso_varying_string module) Slightly reduced test case - still needs the iso_varying_string module. Compiling with 4.4/4.8 and 4.8/4.4 shows that the attached file miscompiled while the big iso_varying_string module is correctly handled. If one compares the dump between 4.4 and 4.8 for the second (the array) SPLIT call, one finds for 4.4 and 4.8, respectively: split_ch (&strar[S.14 + D.1624], &wrdar[S.14 + D.1625], D.1621, &separ[S.14 + D.1626], 0B, MAX_EXPR <D.1616, 0>); split_ch (&strar[S.14 + D.1624], &wrdar[S.14 + D.1625], &D.1621, &separ[S.14 + D.1626], 0B, MAX_EXPR <D.1616, 0>); Note the "&" before D.1621. The latter is: character(kind=1)[1:MAX_EXPR <D.1616, 0>] * pstr.12; D.1964 = &set; D.1619 = __builtin_malloc (....) char_auto (pstr.12, MAX_EXPR <D.1616, 0>, D.1964); pstr.12 = (character(kind=1)[1:MAX_EXPR <D.1616, 0>] *) D.1619; The called function is defined as: elemental subroutine split_CH (string, word, set, separator, back) type(varying_string), intent(inout) :: string type(varying_string), intent(out) :: word character(LEN=*), intent(in) :: set type(varying_string), intent(out), optional :: separator logical, intent(in), optional :: back
