[4.9/5.2/6.0] ICE on function result with procedure pointer component

[Damian Rouson]

All,

I just submitted the code below as Bug 68196 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68196) on be behalf of Bob Numrich.  Could this be related to Bug 36704 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36704), which was fixed, or to Bug 66465 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66465), which remains open?

In case it’s of interest to anyone, the bug report is also now archived in the AdHoc project (https://github.com/sourceryinstitute/AdHoc), which I’m using to automate the demonstration and and checking of bug reports across compilers, compiler versions, and platforms.  In particular, the following folder contains automatically generated output files for Bug 68196 for each of the gfortran versions I have installed on OS X:
