             Bug #: 54096
           Summary: Type bound procedures
    Classification: Unclassified
           Product: gcc
           Version: 4.5.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: badass@vt.edu


running the following:

gfortran -c mod_constants.f90 -Wall -Wextra
gfortran -c mod_files.f90 -Wall -Wextra
gfortran -c class_ships.f90 -Wall -Wextra
gfortran -c mod_io.f90 -Wall -Wextra
gfortran prg_fwb.f90 *.o -Wall -Wextra -fno-strict-aliasing -fwrapv

yeilds:

mod_files.f90:340.85:

broutine setUnitNumber( unitNumber,  numberOfFiles, fileOffset, unit, fType )
                                                                           1
Warning: Unused dummy argument 'ftype' at (1)
f951: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
prg_fwb.f90:13.74:

                              , getShipData                 !& ! procedure
                                                                          1
Fatal Error: Can't open module file 'mod_io.mod' for reading at (1): No such   
     file or directory



we believe the segmentation fault is caused by lines 166 or 167 of mod_io
because an internal compiler error is generated, I don't think it's generating
the ".i" files requested on the bug report instructions.

Please attach the source code to the PR.
Please try a newer version of gfortran as 4.5.3 is fairly old.

Especially for type-bound procedures and related features. For those, you
should use the current release 4.7.1 or the developer version 4.8

You find links to unofficial gfortran builds at:
  http://gcc.gnu.org/wiki/GFortranBinaries

(Cygwin.org does not seem to have a newer build; you might want to try the
MinGW/MinGW-w64 version.)


And as Steve wrote: It is nearly impossible to debug and fix compiler bugs
without a full example.

Sorry about that, I though i had included the source code. I'm working
on getting an updated compiler, but IT here is being difficult and I could
take a day. Thanks for the help, source code is attached.

Seemingly, the mail interface of GCC's Bugzilla doesn't handle attachments.
Thus, please use the web interface to attach the file. Thanks!

Created attachment 27878
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27878
source code

all files are modules except for prg_fwb.f90.
we believe the error segmentation fault has something to do with lines 166-167
of mod_io.f90

Compiles here (w/o errors) on x86-64-gnu-linux with
  gcc version 4.5.3 20110428 [gcc-4_5-branch revision 173117] (SUSE Linux)
However, I do get a link error due to a mishandling of the virtual table in the
compiler. (That's a bug in GCC 4.5 handling of polymorphic variables "CLASS".)

Using GCC 4.6 or 4.8, it compiles and runs, complaining at run time that the
input file could not be found. Thus, it seems as if you need at least 4.6.0
though newer 4.6 releases contain some other bugs fixes and 4.7 contains some
extra fixes for polymorphism. See http://gcc.gnu.org/wiki/OOP for details. (And
for an overview about new features http://gcc.gnu.org/wiki/GFortran#news )

Thanks, will try with newer version of gcc on my end.

I confirm that the code compiles with 4.6.4 up to trunk. No news since almost a
year then closing as fixed. Please reopen if I am wrong.
