I could use it to confirm that there is a bug, but the test case is far too complex for analysis, and it is also not possible to put it in the testsuite. So, at the moment, work on PR 93956 (a F95 wrong-code bug, hence a high priority) is effectively blocked. So yes, I would appreciate a shorter reproducer, especially since I plan to revisit the whole span and pointer area once gcc 10 is out of the door. So, I'll mark this bug as WAITING for now.
