#320 TDM-GCC 5.1.0-tdm-1 : gfortran segfault at reading file

[Petr Kartsev]

1. OS: Windows 7 (64-bit) and Vista (32-bit)
   after updating TDM-GCC, gfortran programs do not work anymore

2. minimal program source:
   ----------- a.f90 ------

integer x
open(1, file='y.txt')
read(1, *) x
close(1)
end

1. compile with 'gfortran a.f90'

3. start the program: we get

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:
 #0  ffffffff

and freeze.

1. for 64-bit version (gfortran -m64 a.f90),
   we get the same but 'fffffffff's are longer and go about 15 times

2. It is caused by both tdm-gcc-5.1.0-3.exe and tdm64-gcc-5.1.0-2.exe
   if I choose

3. either 32- or 64-bit version
4. any installation directory (default or another)
5. default SourceForge mirror (another not tried)
6. option 'TDM-GCC Recommended, All Packages',
   or 'TDM-GCC Recommended, C/C++ ' and check in addition 'fortran' + 'opemnp'

But everything is all right
if I run tdm-gcc-5.1.0-3.exe
and choose 'MinGW Stable, All Packages' (which is missing in 64-bit installer)
then all fortran programs run good.

I.e. version 5.1.0-tdm-1 does not work, 4.8.1-4 does.

Not very urgent, as older version helps, but rather unexpected
