A weird bug in combination of sparse, no debug, QMR, and IGT

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compile ADDA in sparse mode with no debug (can be either with or without 
SSE3, either sequential or mpi mode)
2. Run with -int igt -iter qmr

What is the expected output? What do you see instead?
Iterations stop after the first one with zero residual. The result of the 
simulation is completely wrong.

The problem appears on Win7 64-bit with MinGW, using gcc 4.7.1. It seems that 
the bug appeared after changes introduced by r1213.
