I can't reliably cause this error, but I'm wondering if there's
something I can do to debug why it is occurring. After it is printed,
my OpenMCL image immediately dies without putting me into a debug
Fatal error: : Kernel memory allocation failure.
Can't allocate pointer of size 1073815552 bytes.
I'm using SVN revision r8622 on x86-64.
This seems like quite a large pointer, but, on the other hand, the
machine ought to have more than enough memory to accommodate it.
In case it is relevant, I have also increased the following limits to
2^30 in this OpenMCL image:
But the image usually works fine and I've used it for a long time.
It's only recently that I've been getting these errors. Perhaps I am
pushing the system a little harder than before.
