When compiling llvm-3.0 llvm-tblgen segfaults. 


1) And my initial debug seems to suggest that it crashes before hitting main

2) The last part of the logs of the crash are
make[1]: Leaving directory `/nfs/llvm30/llvm-3.0.src/utils'
make[1]: Entering directory `/nfs/llvm30/llvm-3.0.src/lib/VMCore'

3) Compiling this for 64bit MIPS 

4) I see the same behaviour on the trunk.

Happy to provide any more details
