Looks like the same bug as reported in ICE-in-ifx-with-transfer-for-a-class-variable

Congratulations! This ICE is fixed in a compiler that should be available at the end of the summer (in the northern hemisphere).

I don't know if this the same issue as the other thread. It's hard to know what goes on under the covers. But that one also is fixed in a compiler available later this year.

Thank you for reporting this!

I just confirmed that the ICE with ifx is gone with the compiler that will be available in the next few weeks.

Is this the output you expect?

[ur]

Could not find your output. I expect the program to produce the following three lines

31323334353637383930
64000000
00008040

[Barbara_P_Intel]

My bad on not posting the output. I get the same thing.
