IIRC this was because of a rather amusing behaviour of a Gentoo toolchain with some hardening patches, in this case doing a bit of fun on the stack to make sure it's safe.
A lot of the hardening patches come with disclaimers that some software might break, and as shown by this bug, for good reason.
I'd rather blame the compiler patches for this silly behaviour (and maybe the kernel for not documenting and limiting how much stack VDSO can use)
