@abidh, could you please take a look?

Thanks for reporting this issue. The comment here describe the source of this problem. I thought our implementation would side step the issue but it seems there may be cases where it can still be problem. I will have a look as time permits.

[pawosm-arm]

I was about to file a new bug report, but fortunately, I've found this one. I'm facing the same assertion failing when building dbcsr (one of the CP2K dependencies) with -g -O3 on file https://github.com/cp2k/dbcsr/blob/develop/src/mm/dbcsr_mm_accdrv.F preprocessed into dbcsr_mm_accdrv.F90.

[pawosm-arm]

As a side note, building CP2K's dbcsr seems to be broken again due to some recent commit, it fails like that:

Hi @jieljiel, @pawosm-arm
I opened ##122770 to fix this problem. Please have a look and see it resolved your issues.

@pawosm-arm
If you share the recipe on how to build CP2K's dbcsr with flang then I can test the failing file on my side.
