I have tried to reproduce the aforementioned experiment: JOBU='V', JOBVT='V', RANGE='V', N=1. I have multiplied A by big numbers (using machine parameters from LAMCH) and GESVDX worked just fine, in single and double precisions. (The scaling done in GESVDX is similar to the one done in GESVD so I am wondering what could go wrong). Could I have the code that is invoking GESVDX and leading to the overflow so I can see what is going on?

I was expecting Shandong Lao to send me a code that shows the anomaly he has reported. (Based on his description of the problem, I have not been able to reproduce it.) I suggest we close this bug.
