Hi, all
My friend found a MinGW/MinGW64 Gfortran program io dead lock
issue. I found that the problem is gone on Cygwin GFortran or Linux
GFortran, I don't know it's related with MinGW/MinGW64 CRT or Gfortran
source code. I test 4.5-4.6 series gfortran, all have this question.
The test code :
------------------------------------------------------------
!main.f90
program main
integer :: ret
integer :: fun1
integer :: myfun1
ret=fun1()
write(*,*) ret ! ok:)
write(*,*) fun1() ! death!
end program
function fun1()
integer fun1
write(*,*)1.0
fun1=1
write(*,*) "fun1 end!"
end function
------------------------------------------------------------
When I use Cygwin GFortran to build it
i686-pc-cygwin-gfortran main.f90
a.exe will output
-----------------
1.0000000
fun1 end!
1
1.0000000
fun1 end!
1
-----------------
it works well
i686-w64-mingw32-gfortran main.f90
-----------------
1.0000000
fun1 end!
1 ---> Dead here
-----------------
i686-pc-mingw32-gfortran is the same.
May anyone look through the problem?
Thanks.
