I agree that this patch is a band-aid, possibly for some latent issue.
The suspect patch may have affected the order of resolution.
Note that replacing in the reduced testcase in comment#3:
associate(k=>k_2d)
by
associate(k=>k_2d(:))
avoids the ICE and gives identical code for gcc-12 .. gcc-14. In fact,
the array-spec seems properly set.
I've added Paul in CC, who is more familiar with the associate construct.
