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

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

[Bug fortran/54096] New: Type bound procedures

[badass at vt dot edu]

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54096

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

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.

 (In reply to comment #1)
  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.
