Hi,
I'm having problems with a derived type variable containing
allocatable components declared shared in an openmp parallel
section. I've attached a minimal code to reproduce the problem
below. It executes when compiled with Ifort versions 11.0, 11.1, 12.0,
12.1, but crashes with 13.0, 13.1, 14.0, partially depending on
optimization flags. I typically get the error message:
forrtl: severe (151): allocatable array is already allocated
even though the print statement tells me it's not. I'm not completely
sure the code complies with the openmp specification, but at least I
cannot see an obvious problem. Any feedback would be appreciated.
All the best,
John
