You are on the right track here. But in fact the problem is in the code, not
the compiler. The reference cblas author copied the dsdotsub.f file to
sdsdotsub.f as a starting point for editing, but didn't complete the edits
properly. He left the calling argument signature unchanged, whereas it
requires an extra scalar parameter. It's surprising to find an actual coding
error in code from netlib, but there it is.
I am requesting a new upload shortly. Have a great weekend.
