This is easy to debug because you have a version that works. Run both versions in separate windows each in a debugger and put a break point in the dgeev_ function. When it gets there check that it is the same dgeev_ function in both cases and check that the inputs are the same then step through both to see when things start to change between the two. > > However, on the same machine, if I use the interface in a separate main() > function without linking to any of the libraries except lapack and blas, then > I get expected results. > > Also, this problem does not show up on Mac. > > I am not sure what could be causing this and don’t quite know where to > start.
