Emulator

the following is what i think (within my limited knowledge) would be needed for a bug report.

system:
crunchbang linux 64 "wheezy"
thinkpad t420
intel i7 vPro

followed instructions for compiling on linux from dolphin wiki:
http://code.google.com/p/dolphin-emu/wiki/Linux_Build

googled error code, found match on here says its resolved:
http://code.google.com/p/dolphin-emu/issues/detail?id=5347

i double checked my code against this bugfix but i didnt get too far:
http://code.google.com/p/dolphin-emu/source/detail?r=722480cb2e86

here is the error i get:
