It's helpful that indexes are checked in debug mode.  Unfortunately, I find 
it impossible to get gdb to set a breakpoint on the exception being raised, 
probably due to the use of a macro for BOOST_UBLAS_CHECK.

Perhaps if a function was called to raise the exception, say

boost_raise (exception e) ...

Then it would be easier to put a breakpoint on this function.
