[Patch, fortran, pr67451, v1] [5/6 Regression] ICE with sourced allocation from coarray

[Andre Vehreschild]

Hi all,

unfortunately was my last patch for pr67451 not perfect and introduced
regressions occurring on s390(x) and with the sanitizer. These were
caused, because when taking the array specs from the source=-expression
also its attributes, like coarray state and so on where taken from
there. This additionally added a corank to local objects to allocate,
that were no coarrays overwriting data in the array handle. The attached
patch fixes both issues.

The patch for gcc-5 is not affected, because in gcc-5 the feature of
taking the array spec from the source=-expression is not implemented.

Bootstrapped and regtested ok on x86_64-linux-gnu/F23.

Ok for trunk?

Regards,
	Andre
