[Qemu-devel] Segmentation Fault while running tests.

[Julio Faracco]

Hi guys.

I'm trying to run the QEMU tests for i386 and x86_64 architectures but
they are returning some errors.
I'm using the most update version from git tree and my system is Ubuntu 14.04.
Take a look at this segfault errors.

$ make test

Is it normal?

I disable gnutls for possible errors.
My configure options.
