Itmight be worth taking a look at the assembly code immediately around the crash point, especially if you could also
getthe corresponding code from 9.4.8.
I've already built 9.4.8, passing all tests. I can try to build 9.4.7 to reproduce that crash. I can also try to build
9.4.7with just the relevant commit (0045691) applied to resolve that crash.
But I need more information / pointers to documentation on how to find and provide the information you need, as I have
noexperience with looking at assembly code.
