A normal off the shelf install uses -video d3d so testing such without changed video works fine. I presume your .sym file doesn't match your binary file because the stack crawl names do not match up to running breakout at all. Anyway, I can confirm crashes and I've placed my stack I got with 64-bit binary for breakout. I also noticed there is breakage using -video bgfx and the pong.cpp driver as well - so issues are not exclusive to 64-bit.
