gfortran TDM 5.1 problem

(1/1)

gd_on:
I tried your new 17.12 C::B provided with gfortran (codeblocks-17.12mingw_fortran-setup.exe).
I think you should not distribute this gfortran version (TDM 5.1.0) because it is bugged (no such problem with TDM gcc 5.1.0).
This is not new. Version TDM 4.9.2 had not this bug. It has been corrected in official 5.2 version, and it works also with recent official versions. Its OK too with 6.4 reckless version (except a problem with an empty drive, but it's an other problem already signaled somewhere in the forum).
See the gfortran test case in attachment.

According to this bug report:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66861

this bug was introduced in version 5.1 and corrected in version 5.2.

The bug is in the version 5.1.0 of the file "libgfortran-3.dll" located in the default installation folder:

C:\Program Files (x86)\CodeBlocks\MinGW\bin

A newer version 5.3.0 of this file can be found in file "libgfortran-5.3.0-3-mingw32-dll-3.tar.xz" at:

https://sourceforge.net/projects/mingw/files/MinGW/Base/gcc/Version5/gcc-5.3.0-3/

This file can be opened in e.g. WinRar and version 5.3.0 of the file "libgfortran-3.dll" can be extracted. By replacing the existing version 5.1.0 file with the version 5.3.0 file in the default installation folder mentioned above, reading from files works again.

The gfortran test case in the attachment in the post above works now.

cool. 8)
nevertheless, mixing 5.1 and 5.3 gfortran versions may cause other problems (but may not  ::) ). I'll try that.
