Source code for minimal reproducer

Hi,

I'd like to report an internal compiler error (ICE) when using the SHAPE
intrinsic on assumed-rank arrays on GFortran 10.3.0 (Ubuntu
10.3.0-1ubuntu1~20.04). I have tested the code on godbolt.org for various
versions of GFortran. Version 11 and newer seem to correctly produce an error
message instead of producing an ICE, but all older versions reproduce the ICE.

A minimal reproducer is attached here.

Thanks,
Wileam Y. Phan
