failed to reallocate 163840000 bytes
Return value 0. Terminating...
Looking around for this error suggested that memory might be the case, but I watched the memory used and there was still nearly 4GB of RAM free. There are also a few hundred GB of disk space, so it's not that either.

This is using MSieve 1.52 SVN945 on Windows 7 64-bit. Any ideas?

Edit: The number is the cofactor of 11^238+5^238 (C149, SNFS difficulty = 213). I've done a C142 myself, so unless I was right at the edge of something, I don't know why this would fail.
Edit 2: Using the 1.51 official version from Jeff Gilchrist's site (the 64 bit i7/i5 one) works.
