We've heard similar reports before but it's challenging to find the problem. I can't reproduce the problem on my 32-bit Debian system by just, for example, switching to GCC 4.6. What's in config.h and config.log? How many cores does the system running the build have? (It would be equally useful to have these answers from anyone experiencing this problem.)
