I was using 31-bit (with the -m31 flag) S390 cross-compiling with GCC 11.


When something weird happened:

https://github.com/udos-project/flatboot/blob/60046ae0d6cee23348359b7f94a312332a1357b2/stage2/stivale.c#L383


Here we can see the declaration of a struct, however when i declare the 
same struct (but in a function context) - the code below mishandles the 
given values (start_cc and start_hh) - if i use the declaration instead 
of making a struct in the function stack the start_cc and start_hh 
fields are correct (cc should never be above 100 (decimal) normally)


I think this is a bug because the structs have the same attributes and 
the same fields, with the same order... so their behaviour should not 
change?
