Hi!
svdcmp in sander/ncsu-rmsd.F90 (AmberTools15) have numerical problems at
higher optimization levels.
The ncsu/smd test fails with intel (15.0) at -O2.
Attached is a patch that replaces the call to svdcmp in dstmev with the
corresponding lapack routine (xGESVD) making the test work at full
optimization.
I've only replaced this one call at the moment since i didn't want to
spend too much time doing it in case it gets rejected.
