Title: fortran open statement crash
Post by: karaul on June 12, 2018, 04:01:28 pm

I downloaded and started new fortran application in CB 17.12 and put this simple code into main.f95

program main
    integer i
    OPEN (3,file='test.dat')
    READ (3,*) i
    CLOSE (3)
    write(*,*) ' i=',i
end

Then, successfully compilied and builded with gfortran as compiler, and it crashes with

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

 C:\Program Files (x86)\CodeBlocks\MinGW\bin> .\gfortran.exe --version

Thank you for the quick answer. Unfortunately, the suggested fix to replace "libgfortran-3.dll" does not work.

So, I need to change fortran compiler. I do not know how to do it yet, but it is hopefully described in the manual. 

PS: I used mingw from here https://sourceforge.net/projects/mingw/files/MinGW/Base/gcc/Version6/
With this replaced compiler, it works now.
