From: "mikko dot lyly at csc dot fi" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug fortran/27046] New: gfortran print flush in dll Date: Wed, 05 Apr 2006 15:31:00 -0000 [thread overview] Message-ID: <bug-27046-12481@http.gcc.gnu.org/bugzilla/> (raw) PRINT* in gfortran 4.2.0 compiled dll's needs CALL FLUSH to perform correctly when called from gcc (3.4.2, 3.4.5, 4.1) compiled main. Reproducible sample: $ gfortran -shared -o ftesti.dll ftesti.f90 ftesti.f90: ----------- subroutine print_from_gfortran(txt) implicit none character :: txt print *,txt end subroutine print_from_gfortran $ gcc -o ctesti.exe ctesti.c ctesti.c: --------- #include <stdio.h> #include <windows.h> void print_from_gcc(char* txt) { printf("%s\n",txt); } int main(int argc, char** argv) { HINSTANCE handle=LoadLibrary("ftesti.dll"); FARPROC print_from_gfortran=GetProcAddress(handle,"print_from_gfortran_"); print_from_gcc ("c"); print_from_gfortran("f"); print_from_gcc ("c"); print_from_gfortran("f"); return 0; } Now, running ctesti.exe produces c c f f Correct output should be c f c f Adding CALL FLUSH in ftesti.f90 fixes the case: ftesti.f90: ----------- subroutine print_from_gfortran(txt) implicit none character :: txt print *,txt call flush end subroutine print_from_gfortran -- Summary: gfortran print flush in dll Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: mikko dot lyly at csc dot fi GCC host triplet: i686-pc-mingw32 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27046
