MemTest86_v5 is going to be released with UEFI support: http://www.memtest86.com/technical.htm#new
Is it worth changing from Memtest86+ to MemTest86 ??

Forget it. MemTest86_v5 is not GPL, the last one was 4.3.6.

OK, I compiled it with gcc-3.4 and it seems to work. I will push it and
I will focus on the gcc-4.8 fix later.

Patch fixes non-working binary with later GCC versions.
I have been working on this problem for a while. Disabling the inline-
functions called-once optimization fixes the problem.
I also ran the static analyzer Cppcheck, and solved an array out-of-
bounds bug, and an incorrect pointer bug.

Hi,
thanks for the patch, I will apply it with one minor change. I have already used:
- for(i = 0; i < sizeof(possible_nhm_bus); i++) {
+ for(i = 0; i < sizeof(possible_nhm_bus) / sizeof(possible_nhm_bus[0]); i++) {
I will keep it, because it is more generic solution than the hardcoded
number of iterations.
Could you provide more information about the -fno-inline-functions-
called-once. What it fixes and why?

I like the more generic way of getting the size of an array in C. I've
never seen this technique before, and I'll have to look into it.
About the -fno-inline-functions-called-once optimization:
I do not understand what it fixes or why. I will do more research into
the problem and report back what I discover.
This patch is part of my larger effort of improve Memtest86+'s SMP mode.
It always locks up hard on my Intel Core 2 Quad machine when in SMP.
Once I find the deadlock issue my goal will be to improveimprove SMP
performance.
Here is my project page: github.com/oraac/memtest86--SMP
If anyone here want's to help I'd be happy to get you a SSH key for
commit access.

Thanks.
I probably haven't encountered this problem, because I am using -O0
instead of -O1, i.e. no inlining at all. I will also keep this as is, it
may resolve other hidden problems.
