Summary0000170: stage 2 ssdb build failure on goliath
DescriptionBuilding the stage 2 ssdb library with rotd-2010-11-24 fails on goliath, ssdb.err is:

Uncaught Mercury exception:
Software Error: var_locn.m: Unexpected: clobber_lval_in_var_state_map: empty state
Stack dump not available in this grade.

This in asm_fast.gc, with -O5 and --intermodule-optimisation.

The last working compiler on goliath was rotd-2010-10-19 (between then and now the machine
was down for about a week due to memory troubles).

I have committed a workaround for this in ssdb/Mercury.options.
