[Bug fortran/37523] New: data syncronisation error with openmp


When running the attached code (compiled with -fopenmp) I see intermittent
'WUH' in my output, which should not happen. Wasting some cycles between the
initialization of the array and the start of the DO loop (by printing some
data) works.

jbook:optidus-tng spaans$ LANG=C gfortran -v
Using built-in specs.
Target: i386-apple-darwin9.4.0
Configured with: ../gcc/configure --prefix=/usr/local/gfortran/
--with-gmp=/opt/local --with-mpfr=/opt/local --enable-languages=c,fortran
--no-create --no-recursion
Thread model: posix
gcc version 4.4.0 20080909 (experimental) (GCC) 
jbook:optidus-tng spaans$ gfortran -fopenmp gfortranbug-testcase.f90 -o
gfortranbug-testcase
jbook:optidus-tng spaans$ for a in `gseq 1 1000`; do ./gfortranbug-testcase  ;
done |grep WUH
STOP WUH!
