Can you maybe post stack trace from GDB after crash? Also check what address is dereferenced. Static will probably have different address than non static. aarch64 has some security and atf, maybe that is causing the problem? This is just a wild guess. Check failing instruction, dump info from it like addresses, and then do the same for working static data. Maybe this will shed some light onto this problem. It's good to know which instruction is failing and what arguments it takes. -- .-----------------.-------------------.----------------------.-----------------. | Michal Lyszczek | Embedded C, Linux | Company Address | .-. opensource | | +48 727 564 419 | Software Engineer | Akacjowa 10a; 55-330 | oo| supporter | | https://bofc.pl `----.--------------: Brzezinka Sredzka PL | /`'\ & | | GPG FF1EBFE7E3A974B1 | Bits of Code | NIP: 813 349 58 78 |(\_;/) programer | `----------------------^--------------^----------------------^-----------------'
