Hi,
For the record, thanks to the GCC compile farm, I determined that this
bug has been fixed in gcc trunk by
http://gcc.gnu.org/viewcvs?view=revision&revision=145494

Hi,
I played with the example provided by Kumar Appaiah, and narrowed the
problem down to zdrot; after copying zdrot.f into the same directory
as zgesvd_ex.f:
$ gfortran -O2 -c zgesvd_ex.f
