Would it be possible to list the kernel version (full version including the minor version) on which the test works or crash? You are talking about "3.10" without the minor version. It may be a regression in the kernel.

Example of change in Linux kernel 3.10.17:

    ARC: Fix signal frame management for SA_SIGINFO
    
    commit 10469350e345599dfef3fa78a7c19fb230e674c1 upstream.
    
    Previously, when a signal was registered with SA_SIGINFO, parameters 2
    and 3 of the signal handler were written to registers r1 and r2 before
    the register set was saved. This led to corruption of these two
    registers after returning from the signal handler (the wrong values were
    restored).
    With this patch, registers are now saved before any parameters are
    passed, thus maintaining the processor state from before signal entry.

I would like to make sure that the bug is not a kernel bug.
