Unfortunately the crash happened in Koji:
https://koji.fedoraproject.org/koji/taskinfo?taskID=79160330
I'm not able to reproduce it locally, which is strange. I've got an
armv7 guest which has the same version of gcc, binutils and annobin,
yet it does not crash compiling the same file.
I wonder if anyone can manage to reproduce this and capture the
/tmp/*.out file? In theory all you need to do is build qemu from
dist-git on armv7.
Alternatively, can anyone think of a reason why this crash would
happen in Koji but not in an armv7 guest (on aarch64 host)?
Rich.
