AFAICT it fixes the problem for 64 bit mode only. In 32 bit mode the ICE is
gone, but I get at run time

i_good=         1         3         5
 i_bad=         1**********         3

Did you regtest with -m32? I see gfortran.dg/associated_target_5.f03 failing at
execution time with -m32, as well as the first test in pr57522
