This is a stupid testcase, the failure should be ignored.
The glibc values for MINSIGSTKSZ and SIGSTKSZ must be large enough to
cover all known kernels, so that user programs will run on any kernel
and with any usage of vmx, htm and whatever else changes context size.
The values in the kernel on the other hand are for testing whether a
given binary will run on that kernel. In the absence of knowledge
regarding whether a binary makes use of htm or vsx, the kernel values
must be the minimum allowed on all known kernels. Otherwise an old
binary that doesn't make use of vsx or htm will no longer run on a new
kernel.
** Changed in: linux (Ubuntu)
Status: Confirmed => Invalid
