Matt Bandy <matt.ba...@thq.com> added the comment: Sorry, I should have been more precise. I did use static for the variable I declared at file scope. Looking at the disassembly again also reminded me of something I should have mentioned in the original bug report: at least when using Visual C++ 2008, in the release build the compiler optimizes out the repeated reads even with the original code, so the generated assembly with the local variable patch is actually identical. I encountered the bug using the debug build of the interpreter, where that optimization does not occur and the memory is actually read three times.
