I have now tried all the solutions that have been suggested.
I am able to make one call to a simple routine give exactly the same
results with the two ways of running the program when I use crt_fp8.o.

However, when I run the full code in any of the suggested ways, the
same happens. The standalone program runs fluently, but the mex
version run within matlab gets stuck. I am getting to the conclusion
that I probably was a little imprecise when I said the same code is
used in both cases. This is in fact not true. I do a few things
differently (however, this seems to make no trouble) and I do pass
fortran a few variables forth and back from matlab over c. Maybe it is
just not possible to have exactly the same results when this is done?
Maybe matlab and persistent mex arrays somehow are able to change some
digits of the numbers? In addition the program does several nested
iterations until some accuracy, so probably I will not be able to have
exactly the same?
