Sage 5.4 build failure on Ubuntu 10.04 32 bit

Sage 5.4 fails to build for me on Ubuntu 10.04 32 bit:

You might try typing 'sage -ba' or write to sage-support with as much information as possible.

It's a hardware problem, a bit got flipped in that file. The string
should be __pyx_clineno instead of __pqx_clineno. You should run memtest
to check for memory problems.

Thanks for the diagnosis and advice. I editted that file, and sage 5.4 built successfully. I then extracted the tarball into a new directory, and did another complete build from scratch, which worked. I'll do some memory testing. Or, maybe it was a VM glitch, as my Ubuntu is running in a VM.

Thanks,
