--- Comment #12 from marcus at mc dot pp.se --- If it's just a lack of hardware, a regular Raspberry Pi 3 can be used. Compiling gcc on one takes 18.5 hours though... :-) But yeah, if it's a miscompilation of the compiler, then it's probably not going to be straightforward to nail it down. Can I run the testsuite on the stage1?
