Thought I recognised this, it's been on the linux-mips.org mailing list. 
Here is a response to that OP:

The likely cause is:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33755

As indicated in the PR, Richard has a patch that he is testing.  I would
think that by the time gcc-4.2.3 is released that it would be fixed.

I would recommend using a non-4.2.x version of gcc until the problem is
fixed.

I guess 4.2.1 is broken :)
