Hi Timur,

That isn't a variable, that is the first line of a struct declaration. 
You cut some pretty important information: what the struct is, the 
actual variable in question, and whether it is initialized.

I'm guessing from the name "eeprom" that you have a non-zero initializer 
on it???  Does it make a difference if it is uninitialized, initialized 
to {0}, or initialized to non-zero values?

Does it make a difference if it is packed or not (my guess: much less 
likely than initialization to cause works/broken).

Best regards,
