Thanks. Can you check whether GNU libsigsegv builds correctly on this platform? Most likely it is a bug in either kernel, libc, and/or libsigsegv not interacting correctly, which results in m4's use of libsigsegv no longer being able to detect stack overflow. If we can get libsigsegv patched to work around the problem, then the failure would disappear from m4. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
