Actually this looks like a duplicate of issue28055.

I know this is a bit late but I wanted to share...
OpenCSW has a build farm with Solaris machines and Sparc hardware. The farm provides x86 and Sparc machines with Solaris 9 through 11.
I believe OpenCSW operates in the same spirit as GCC compile farm. They welcome open source developers and upstream maintainers to help ensure packages build and run on Solaris machines.
You can read about it at
https://www.opencsw.org/extend-it/signup/to-upstream-maintainers/ .
If Python is performing memory access patterns as discussed in the report then it would probably benefit the project to test on a Sparc machine with Solaris 11.
