AOCC 4.1 flang: "0: ALLOCATE: xxx bytes requested; not enough memory"

I am using Flang via AOCC 4.1.

Sometimes, I encounter an error saying "0: ALLOCATE: xxx bytes requested; not enough memory", even though the same code works well with the Classic Flang 15.0.3, nvfortran 23.7, gfortran, ifort, ifx, and nagfor.

Is it a known problem?

Those who are interested may have a look at
https://github.com/libprima/prima Suppose that your machine has AOCC 4.1 installed. Cloning this code and run

git checkout 54e66dd && cd fortran/examples/cobyla && make clean && make dtest
 
you will get

Sorry that I do not have a minimal working example. I just want to check whether anyone else has encountered the same problem. Thank you very much!
