Hi,
We have a somewhat serious problem with gfortran on x86/mingw32 system:
program test
implicit none
character(len=10) :: string
integer :: m,n
do m = 1,1000
do n = 1,10000
write(string,*) 'nice'
end do
print *,'Check memory and handles and press ENTER...'
call flush
read(*,*)
end do
end program test
Start the task manager and run the small program above to see memory and
windows handle usage (1 / internal write) to skyrocket.
The fortran versions i see this include the latest 4.3 & the mingw 4.2_sjlj
versions at least:
$ gfortran -v
Using built-in specs.
Target: i386-pc-mingw32
Configured with: ../trunk/configure --prefix=/mingw
--enable-languages=c,fortran --with-gmp=/home/FX/local --with-ld=/mingw/bin/ld
--with-as=/mingw/bin/as --disable-werror --enable-bootstrap --enable-threads
--disable-nls --build=i386-pc-mingw32 --enable-libgomp --disable-shared
Thread model: win32
gcc version 4.3.0 20080127 (experimental) [trunk revision 131883] (GCC)
