I was able to verify it on W7 Professional, x64. ST build 3019. Below is the dump summary, though I don’t know how helpful it will be to tracking down this issue. There were also some XML files, but I didn’t see anything that would help track down any issues. That being said, if those would be helpful, let me know.

Thanks for the confirmation. It turns out the issue is a pointer arithmetic underflow bug in Oniguruma that only manifests itself on Windows 7 x64, and not Windows 8, due to the low heap addresses issued by the Windows 7 x64 malloc implementation. Should have it fixed shortly.
