I did a fresh clone of the QEMU repository. Then tried building QEMU. This is the error I saw: CC contrib/ivshmem-client/ivshmem-client.o CC contrib/ivshmem-client/main.o LINK ivshmem-client collect2: error: ld terminated with signal 11 [Segmentation fault] make: *** [ivshmem-client] Error 1 make: *** Deleting file `ivshmem-client' It is different from the last error, but it still involves something called ivshmem.
