Currently the stack frame size limit is set to 4096 and it started to cause an error like this:
virshtest.c:253:1: error: stack frame size of 5512 bytes in function 'mymain' [-Werror,-Wframe-larger-than=] mymain(void) ^ 1 error generated.
Increase it to 6144.
Worth to mention that it's started to show up after updating to clang 3.6.
Any comments on this?
Have you reported a possible clang regression bug to the clang folks? Or is the new clang version the first one to support what was originally only gcc's -Wframe-larger-than? At any rate, why does clang require a larger stack than gcc? It sounds like in addition to fixing the virshtest.c file to quit stack-allocating such a large amount of space, that you should also be letting the clang compiler folks know about their weakness. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
